Wildcards in Queries

Topics in this Section

Use wildcard matching sparingly, because it slows IDOL server performance.
You can use these wildcards in query text and field text queries:
You can use the UnstemmedMinDocOccs parameter in the [Server] section of the configuration file to specify the number of documents in which a term must occur to consider it in a wildcard search.
NOTE To use wildcards to search for numbers, set SplitNumbers (described in the [Server] configuration section of the IDOL server online help) to false.
