When you enter the Search Types view, first check "Enable Advanced Searches", which activates the other controls. This migrates the collection to Greenstone 2.4 format, which supports for fielded searching, and means that (a) the index design is different (explained in section 7.5 -- Search Indexes), (b) there are more text fragments to translate (see Section 7.10 -- Translation), and (c) the collection will not be usable under older Greenstone installations. If you later uncheck this field, most of your collection will be migrated back to Greenstone 2.39. However the Librarian Interface cannot convert the new index specifications into older ones, so you will have to re-enter them manually.

To add a search type, select it from the "Search Types" list and click "Add New Search Type". Each type can only appear in the list once.

To remove a search type, select it from the "Currently Assigned Search Types" list and click "Remove Selected Search Type". The list must contain at least one search type.

To change to order of a search type, select it from the list and click "Move Up" or "Move Down".
