Use the CASE
modifier with the WORD
or
WILDCARD
operator to perform a case-sensitive search, based on
the case of the word or phrase specified. The modifier only needs to be
specified if search words exclusively containing either uppercase or
lowercase letters need to be found in the documents. When mixed uppercase
and lowercase characters are included in a query, the search engine finds
case-sensitive matches automatically.
To use the CASE
modifier, you simply enter the search word
or phrase as you wish it to appear in retrieved documents -- in all
uppercase letters, in mixed uppercase and lowercase letters, or in all
lowercase letters.
For example, to retrieve documents that contain the word "apple", all in lowercase letters, you can enter the following:
<CASE> <WORD> apple
Only those documents that contain the word "apple" will be selected. Occurrences of "Apple", "apples", or "APPLE" will not be selected.
