This document discusses internet searching and online databases. It provides tips for effective internet searching, including using quotation marks, Boolean operators, and keywords. It also discusses four main steps search engines use to find information: crawling the web, indexing pages, ranking pages, and displaying results. The document then discusses online databases and provides tips for searching them such as using appropriate search terms, selecting relevant databases, starting with general searches, and using advanced search features.
Internet Search Tools
There are three main categories of internet search tools: individual search engines, meta-search engines, and subject directories. Individual search engines like Google use programs to match search terms to web pages and return a large volume of results without filtering. Meta-search engines like Google Custom Search send requests to multiple search engines simultaneously and eliminate duplicates. Subject directories like library databases are maintained by humans to search broad categories and allow narrowing searches, and may include non-HTML formats.

Directories and search engines are methods for finding information on the web. Directories organize web pages into a hierarchical structure on specific topics, classified by human editors. Search engines allow users to search large databases for pages matching search queries. There are general search engines covering many topics and specialized engines for particular topics like news or shopping. Metasearch engines send queries to multiple search engines at once. Effective search strategies include determining the best search engine based on interface, documentation, speed, database size, and relevancy scoring.

The document summarizes the results of clinical trials evaluating bioresorbable vascular scaffolds (BVS). It describes improvements made to the BVS device and platform (Cohort B) based on the findings of an initial clinical study (Cohort A), including making the strut distribution more uniform and the scaffold stronger initially to reduce late lumen loss. Results showed Cohort B had less reduction in scaffold area at 6 months compared to Cohort A and late lumen enlargement between 6 months and 2 years. The studies provide evidence that BVS devices can fully degrade and resorb over time while maintaining vessel patency.About me

Internet Search
Google was founded in 1996 as a research project by Larry Page and Sergey Brin to create a search engine that analyzed relationships between websites to produce better search results than existing methods. It is now a major global technology company headquartered in California. Yahoo was founded in 1994 by Jerry Yang and David Filo as a way to track their personal interests online and later expanded. Meta search engines send search queries to multiple other search engines and databases and aggregate the results, while Boolean search uses operators to narrow search parameters. Google makes money from search ads and commissions on sales, and charges for sponsored links. Google's browser is called Chrome and has advantages like a simple design for fast browsing and an address bar that doubles as a search box

Search engines
A search engine indexes web pages using crawlers or spiders. It builds an index that allows users to search for keywords. Directories created by people may provide more curated results than broad search engine indexes. Popular search engines include Google, Yahoo, and Bing. Boolean operators like AND, OR, and NOT allow refining searches. Settings like safe search and advanced options provide more control over results.
search engines
Search engines index web pages and content to provide relevant results for user queries. There are different types of search engines including general web search engines, vertical search engines that focus on specific content like images or video, enterprise search engines for internal company searches, and social search engines that factor in user interactions. New forms of search continue to emerge like semantic search that leverages metadata to improve relevance and selection-based search that is invoked solely by mouse clicks.

Introduction to internet.
A search engine is a software system that searches the World Wide Web for information and presents search results on search engine results pages (SERPs). Search engines work by using web crawlers to index web pages, then searching their indexes to provide relevant results for user queries. They offer operators like Boolean logic to refine searches. The usefulness of search engines depends on how relevant their results are, and they employ various ranking algorithms to provide the most relevant pages first. Metasearch engines simultaneously query multiple other search engines and aggregate their results.
