Accessing and Using Data
Pass-through of terms
Search terms are passed through to the VDK-level and are interpreted as Verity Query Language (VQL) syntax. No
issues arise if the terms contain only alphabetic or numeric characters. Other kinds of characters might be interpreted
by the language you're using. If a term contains a character that is not handled by the specified language, it can be
interpreted as VQL. For example, a search term that includes an asterisk (*)can be interpreted as a wildcard.
Stop words
The configurable Internet query parser uses its own stop-word list, qp_inet.stp, to specify terms to ignore for natural
language processing.
Note: You can override the "stop out" by using quotation marks around the word.
For example, the following stop words are provided in the query parser's stop-word file for the English (Basic)
template:
a did
also do
an does
and find
any for
am from
are get
as got
at had
be has
but have
can how
Verity provides a populated stop-word file for the English and English (Advanced) languages. You need not modify
the qp_inet.stp file for these languages. If you use the configurable Internet query parser for another language, provide
your own qp_inet.stp file that contains the stop words that you want to ignore in that language. This stop-word file
must contain, at a minimum, the language-equivalent words for or and <or>.
Note: The configurable Internet query parser's stop-word file contains a different word list than the vdk30.stp word file,
which is used for other purposes, such as summarization.
Composing search expressions
The following rules apply to the composition of search expressions.
Case sensitivity
Verity searches are case sensitive only when the search term is entered in mixed case. For example, a search for zeus
finds zeus, Zeus, or ZEUS; however, a search for Zeus finds only Zeus.
To have your application always ignore the case that the user types, use the ColdFusion
attribute of
