This document provides an overview of Boolean logic searching and how it applies to internet searches. It discusses the three Boolean operators - AND, OR, and NOT - and how they combine search terms using set logic and Venn diagrams. While few search engines support full Boolean searches with operators, most use implied Boolean logic where spaces mean AND and symbols like "+" and "-" stand in for operators. Many also provide search forms that allow choosing logic (e.g. "this" or "all" terms) without using operators. The document provides examples of constructing searches using the different methods.

Google Advance Searching- Information System Audit & Control ReportShahzeb Pirzada
What is Advanced Search?
Advanced search enables increased accuracy of search results by using additional syntax to focus the search. One or more search criteria or operators can be combined in order to tailor the results more specifically towards your needs. These operators allow you to find what you're looking for quickly and accurately. For Search Engine Optimizer’s (SEO’s), advanced search operators are essential if you want to ‘peek under the hood’ by doing a much deeper and more accurate web searches.
This lesson teaches CA Draft Library Standards on using advanced search techniques. This skill is put to use using Gale Virtual Reference Library along with the Big 6 research organizer.
Every search system offers a variety of features and special search techniques, and rarely are any two systems searched exactly the same way. There are, however, some common search strategies that you can use for databases and other systems.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Boolean Logic Searching: A Primer … “something about Boolean logic is counter-intuitive for many otherwise intelligent people.”
3. Boolean Logic Searching The Internet is a vast computer database which is searched according to the rules of computer database searching. Much database searching is based on the principles of Boolean logic. Boolean logic refers to the logical relationship among search terms, and is named for British-born Irish mathematician George Boole. On Internet search engines, the options for constructing logical relationships among search terms often modify traditional practices of Boolean searching (see Boolean Searching on the Internet tutorial, following this primer).
4. Boolean Operators Boolean logic consists of three logical operators: AND OR NOT Each operator can be visually described by using Venn diagrams The following slides illustrate how these three operators function.
5. ORlogicQuestion: I would like information about college. In this type of search, we will retrieve records in which AT LEAST ONE of the search terms is present. We are searching on the terms college and also university since documents containing either of these words might be relevant. college OR university
6.
7. the shaded circle with the word university representing all the records that contain the word “university.”
8. the shaded overlap area representing all the records that contain both “college” and “university.”college OR university
9. ORlogic OR logic is most commonly used to search for synonymous terms or concepts. Here is an example of how ORlogic works: ORlogic collates the results to retrieve all the unique records containing one term, the other term, or both of them.
10. ORlogicQuestion: I would like information about college. The more terms or concepts we combine in a search with OR logic, the more results we will retrieve. college OR university OR campus
12. ANDlogic Question: I'm interested in the relationship between poverty and crime. In this search, we retrieve records in which BOTH of the search terms are present. This is illustrated by the shaded area overlapping the two circles representing all the records that contain both the word “poverty” and the word “crime.” poverty AND crime Notice how we do not retrieve any records with only “poverty” or only “crime.”
14. ANDlogic Question: I'm interested in the relationship between poverty and crime. The more terms or concepts we combine in a search with ANDlogic, the fewerresults we will retrieve. poverty AND crime AND gender
16. NEAR: a restrictive AND In addition: a very few search engines make use of the proximity operator NEAR. A proximity operator determines the closeness of terms within the text of a source document. NEAR is a restrictive AND. The closeness of the search terms is determined by the particular search engine. Most search engines default to proximity searching.
17. Combined ANDand ORlogicQuestion: I want information about the behavior of cats. The use of parentheses in this search is known as forcing the order of processing. In this case, we surround the OR words with parentheses so that the search engine will process the two related terms as a unit. The search engine will use AND logic to combine this result with the second concept. Using this method, we are assured that the semantically-related OR terms are kept together as a logical unit. behavior AND (cats ORfelines)
18. NOTlogic Question: I want information about cats, but I don't want to see anything about dogs. This search retrieved records in which ONLY ONE of the terms is present, the one we have selected by our search terms. This is illustrated by the shaded area with the word cats representing all the records containing the word “cats.” cats NOT dogs No records are retrieved in the area overlapping the two circles where the word “dogs” appears, even if the word “cats” appears there too.
19. NOTlogic NOT logic excludes records from your search results. Here is an example of how NOTlogic works:
20. NOTlogic “cats are smarter than dogs” Be careful using NOT: the term you want may be present in an important way in documents that also contain the word you wish to avoid. For example, a Web page includes the statement “cats are smarter than dogs.” The search illustrated above would exclude this document from your results.
21.
22. Boolean Searching on the Internet When you use an Internet search engine, the use of Boolean logic may be manifested in three distinct ways: Full Boolean logic with the use of the logical operators Implied Boolean logic with keyword searching Boolean logic using search form terminology
24. 1. Full Boolean Logic with Logical Operators Few search engines currently offer the option to do full Boolean searching with the use of the logical operators. More often simpler methods of constructing search statements are used, specifically, implied Boolean logic and search form terminology. These methods are covered below.
25. 1. Full Boolean Logic with Logical Operators Experiment by constructing searches using Boolean logical operators. Try some of the search statements shown on the following slides. Compare results from various search engines. Keep in mind that the search engine might require that the Boolean operators be typed in CAPITAL LETTERS. Most search engines provide help pages which explain the kind of searching the site performs.
26. 1. Full Boolean Logic with Logical Operators Question: I need information about cats. Boolean logic:OR Search:catsORfelines Question: I'm interested in dyslexia in adults. Boolean logic:AND Search:dyslexiaANDadults Question: I'm interested in radiation, but not nuclear radiation. Boolean logic:NOT Search:radiationNOTnuclear
27. 1. Full Boolean Logic with Logical Operators Question: I want to learn about cat behavior. Boolean logic:AND, OR Search:behavior catsORfelines This example combines implied ANDlogic—designatedby the space between the word “behavior” and “cats”—with the use of the Boolean OR operator. The safest way to conduct this type of search is to use the advanced search page available on most search engine sites. This will be shown in option #3 below (search form terminology).
28. 2. Implied Boolean Logic with Keyword Searching keyword searchingrefers to a search type in which one enters terms representing the concepts wished to retrieve. Boolean operators are not used. implied boolean logicrefers to a search in which symbols are used to represent Boolean logical operators, and is so common in Web search engines that it can be considered a de facto standard.
29. 2. Implied Boolean Logic with Keyword Searching Question: I'm interested in radiation, but not nuclear radiation. Boolean logic:NOT Search:radiation -nuclear Notice the minus sign (-) in front of the word “nuclear.” In this type of search, the absence of a symbol is also significant, as the space between keywords defaults to either OR logic or AND logic.
30. 2. Implied Boolean Logic with Keyword Searching Question: I need information about cats. Boolean logic:OR Search: [None] There are probably no general search engines on the Web that interpret the space between keywords as the Boolean OR. Rather, the space between keywords is interpreted as AND. To do an OR search, choose either Full Boolean Logic(#1 above) or Search Form Terminology (#3 below).
31. 2. Implied Boolean Logic with Keyword Searching Virtually all general search engines on the Internet default to AND logic. Question: I'm interested in dyslexia in adults. Boolean logic:AND Search:dyslexia +adults or (and usually), Search:dyslexia adults (space implies AND)
32. 2. Implied Boolean Logic with Keyword Searching Question: I want to learn about cat behavior. Boolean logic:AND, OR Search: [none] As noted previously, a space between keywords implies AND; and generally, only use of full Boolean logic retrieves an OR search.
33. 3. Boolean Logic Using Search Form Terminology Many search engines offer an advanced search page with a search form which allows the user to choose the Boolean operators from a menu. Usually the logical operator is expressed with substitute terminology rather than with the operator itself.
34. 3. Boolean Logic Using Search Form Terminology Question: I need information about cats Boolean logic:OR Search:Each result must/should contain one, all, or a combination of subject keywords Question: I'm interested in dyslexia in adults. Boolean logic:AND Search: Each result must/should contain both/all the subject keywords.
35. 3. Boolean Logic Using Search Form Terminology Question: I'm interested in radiation, but not nuclear radiation. Boolean logic:NOT Search:Each result must not/should not contain any of the undesired keywords. Question: I want to learn about cat behavior. Boolean logic:AND, OR Search:Each result must/should contain the specific combination of keywords, if search form allows multiple search logic.
