[Koha] Problems with OPAC

We have a number of problems with OPAC: 1)  Advanced search always searches with “and”, how can we get "or" and "not" to work too? 2) Limiting searches by item type doesn't work. The result is always: "No results match your search for kw,wrdl: bachmc-itemtype:CDAU". There are matching records in the database. 3) Sorting search results only works for "title". We need it to work for "author" and "dates" too. Something's obviously seriously wrong with the search in this system. Any ideas? -- View this message in context: http://old.nabble.com/Problems-with-OPAC-tp27530296p27530296.html Sent from the Koha - Discuss mailing list archive at Nabble.com.
