May someone please give me a helping hand here? We're quite in some pressure to get this stuff to GA @ Jülich and this is one of the more important ingredients.
Many thanks in advance!
Maybe it is a missunderstanding of me but I found a problem with a more complex search pattern in Invenio (1.0 maint). I'm using basic search here with strings to represent the complex search, not the advanced search interface (basically as in many cases I need more than 3 criteria ;) Consider a set of fields where I want to search for specific strings. Say, I want to search for 'A' in field 9201_ and 'B' in 915__ (all exact strings, no fancy expanding or any fuzzy searching, A and B being unique IDs). The query would then be: 9201_:'A' AND 915__:'B' This works as expected. Now things get a bit more complex. I want to find 'B' or 'C' in 915__, in all those records where 9201_ is still 'A'. Therefore, the query should be 9201_:'A' AND (915__:'B' OR 915__:'C') right? However, this just does not work. It does not yield any results though in the case I used C is actually a subset of B (ie. each record that sets B also has C set, I'd thus expect the same results as in the first case.) Leaving out the braces gives a result, but AND preceeds OR so not what I expect either. What am I doing wrong here? Many thanks in advance! BTW: The above is a simplified query, the full flexed thing would be: 9201_:'I:(DE-Juel1)ZB-20090406' AND (915__:'StatID:(DE-HGF)0100' OR 915__:'StatID:(DE-HGF)0110') though I guess that the quotes prevent anything strange to happen. -- Kind regards, Alexander Wagner Subject Specialist Central Library 52425 Juelich mail : [email protected] phone: +49 2461 61-1586 Fax : +49 2461 61-6103 www.fz-juelich.de/zb/DE/zb-fi ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
