2. The search strategy and its
prerequisites
• The search strategy encompasses several steps and
levels of work in information retrieval meadow
Cochrane mention that the search strategy includes
at least three
• Decision points that a searcher has to reach three are
many issues that need to be considered while
formulating an appropriate search statements these
are-
• The concepts or facets to searched and their order
• The feature (s) of the retrieval system concerned.

3. Search Strategy with Boolean
Method
•The Boolean method ofsearching began with
George Boole (1815–1864).
•A mathematician who created the method for
symbolic logic.

4. • Using the Boolean method, searches for
research information can be simple or
complex depending on the type of
information and the detail desired.
• Boolean techniques include using the words
AND, OR, and NOT in combination and with a
variety of other techniques to achieve and
find results.

5. • AND—Use when searching for documents
containing both words that AND separates.
• OR—Use when searching for documents that
contain one of the terms that OR separates.
• NOT—Use to exclude a term from the search.

6. Boolean Techniques
Using AND-
• When using AND, a search is narrowed.
• AND can be used more than once in a search
string; for
• example: FISH AND CHIPS
Will retrieve all record with the search terms
Fish and CHIPS occurring in the same record.

7. • Using OR
• The Boolean OR lets a search be conducted for
either or both of the keywords used in a
• search. For example
• FISH OR CHIPS
Will retrieve a;; those records where either of
the search terms occur

8. • Using NOT-
• The NOT operator narrows a search by
excluding the keyword that is directly after
the NOT. For example-
• FISH NOT CHIPS
Will retrieve all those records where the
search term FISH occurs and the same time
the term CHIPS does not occur
• NOT should be used carefully in the search
process because it may inadvertently exclude
articles that may be of interest.

9. • Limiting Searches
The database in a text retrieval system comprises
different fields containing different items of
information. The user in his or her query
formulation should be able to limit the search in
one or more fields, and text retrieval software
usually provides this facility. This is also known as
field searching, whereby the user can specify that
the search terms are to be looked for in one or
more fields .

10. • For Examples-
BIRD.PET
will retrieve all records where the search term
BIRD occurs in the paragraph (field) named
PET, and from Micro- CDS/ISIS

11. Truncation
• Truncation allows a search to be conducted for
all the different forms of a word having the
same common root. As an example, the
truncated term COMPUT* will retrieve items
on
COMPUTER,COMPUTING,COMPUTATION,COM
PUTE, etc.

12. • For Example-
FISHS-
Will retrieve all records with words beginning
with FISH ,e . g . FISH,FISHES,FISHY, FISHING ,
etc.
