Hi! About bracket reduction: this is what I added to my code. It is not that simple as I generate them from othet ops.
I agree, that it would be a good idea if the query parser removes unnecessary brackets. Would avoid trouble. I'll try to build a sample against the demo site. -- Kind regards, Alexander Wagner Subject Specialist Central Library 52425 Juelich mail : a.wag...@fz-juelich.de phone: +49 2461 61-1586 Fax : +49 2461 61-6103 www.fz-juelich.de/zb/DE/zb-fi ----- Reply message ----- From: "Tibor Simko" <tibor.si...@cern.ch> Date: Thu, Feb 27, 2014 14:28 Subject: Search & Bracketing To: "Wagner, Alexander" <a.wag...@fz-juelich.de> Cc: "project-invenio-devel@cern.ch" <project-invenio-devel@cern.ch> On Thu, 27 Feb 2014, Wagner, Alexander wrote: > The ind:val-example I gave, where you noticed it is perfrctly ok, is > actually broken on JuSER. Would you have an example that fails on our demo site? >> (ind:"val1" and ind:"val2") and ((ind:"val3" or ind:"val4") or >> ind:"val5") If you use this query literally, then please note that several pairs of parentheses are not needed here, as they are chaining within the same AND or OR sequence. You can reduce the above to: ind:"val1" and ind:"val2" and (ind:"val3" or ind:"val4" or ind:"val5") The logic being: (A and B) and ((C or D) or E) == A and B and (C or D or E) It may be helpful to the query parser to always reduce the number of incoming parentheses.
