Modifiers
You combine modifiers with operators to change the standard behavior of an
operator in some way. For example, you can use the CASE modifier with an operator
to specify that you want to match the case of the search word.
The following table describes the available modifiers.
Modifier Description
CASE Specifies a case-sensitive search. Normally, Verity searches are
case-insensitive for search text entered in all uppercase or all
lowercase, and case-sensitive for mixed-case search strings.
The expression:
<CASE>J[JAVA, java]
Searches for “JAVA” and “Java.”
MANY Counts the density of words, stemmed variations, or phrases in a
document and produces a relevance-ranked score for retrieved
documents. Use with the following operators:
•
WORD
•
WILDCARD
•
STEM
•
PHRASE
•
SENTENCE
•
PARAGRAPH
Here is an example:
<PARAGRAPH><MANY>javascript <AND> vbscript
You cannot use the MANY modifier with the following:
•
AND
•
OR
•
ACCRUE
•
Relational operators
NOT Use to exclude documents that contain the specified word or phrase.
Use only with the AND and OR operators.
Here is an example:
Java <AND> programming <NOT> coffee
ORDER Use to specify that the search elements must occur in the same order
in which they are specified in the query. Use with the following
operators:
•
PARAGRAPH
•
SENTENCE
•
NEAR/N
Place the ORDER modifier before any operator, as follows:
<ORDER><PARAGRAPH>("server", "Java")
