Word-Level Concept Searching


With the concept operator--the exclamation point--you can perform a concept search for an individual query word, as opposed to using the Search Screen's Concept button, which considers your entire query. Like the Concept button, the concept operator dynamically generates a list of terms statistically related to the word to which the operator has been appended. PLWeb Turbo then performs a search for the original query word and the most significant related terms.

Syntax:

word!
Examples:

tribal! politics in South Africa!
In this example, concept searches will be performed for the words tribal and Africa, but not for politics or South.

If search stemming is on-as it is by default-the following query:

run!
will search for terms related to variants of the word-run, runs, running, etc. If stemming is off, the query will search for terms related only to run.

If search stemming is on, the following query:

run#!
in which stemming is disabled by the exact match operator, will search for terms related only to run.
