Highlighting Query Terms

In text query applications, you can present selected documents with query terms highlighted for text queries or with themes highlighted for ABOUT queries.

You can generate three types of output associated with highlighting:

• A marked-up version of the document

• Query offset information for the document

• A concordance of the document, in which occurrences of the query term are returned with their surrounding text
