TermExpand

Allows you to specify misspelled or Wildcard terms and return all matching terms in IDOL Content Component. You can also use TermExpand to return the term phrases that internal synonym links (returned by a query with the Synonym parameter) correspond to.

You can also restrict the term expansion for Wildcard or misspelled terms to terms in UnstemmedTrackFields by adding a field restriction.

NOTE: By default, TermExpand does not apply document security to the results. You can enable security by setting the SecureTermExpansion configuration parameter. In this case you must provide the SecurityInfo with the security information for the user, and TermExpand returns terms from only documents that the user has permission to access.

TermExpand returns the tag <autn:secure_expansion>, which has the value True when you have turned on SecureTermExpansion, or when you do not have security configured.

http://12.3.4.56:9100/action=TermExpand&Text=Mauri*:Country&Expansion=Wild
