- * Revision 1.6 1998-01-29 13:36:01 adam
- * Structure word-list, free-form-text and document-text all
- * trigger ranked search.
- *
- * Revision 1.5 1997/11/19 10:22:14 adam
- * Bug fix (introduced by previous commit).
- *
- * Revision 1.4 1997/11/18 10:05:08 adam
- * Changed character map facility so that admin can specify character
- * mapping files for each register type, w, p, etc.
- *
- * Revision 1.3 1997/11/17 15:35:26 adam
- * Bug fix. Relation=relevance wasn't observed.
- *
- * Revision 1.2 1997/10/31 12:39:30 adam
- * Changed log message.
- *
- * Revision 1.1 1997/10/27 14:33:06 adam
- * Moved towards generic character mapping depending on "structure"
- * field in abstract syntax file. Fixed a few memory leaks. Fixed
- * bug with negative integers when doing searches with relational
- * operators.
