Subject: Loose the query parsing so that Pazpar2 only returns error if _all_
X-Git-Tag: PAZPAR2.1.0.2~89
X-Git-Url: http://lists.indexdata.dk/?a=commitdiff_plain;h=c7e28063b2365987df7adc35db6786732b8e233f;p=pazpar2-moved-to-github.git

Loose the query parsing so that Pazpar2 only returns error if _all_
query conversions fail (rather than _any_). This means targets that do
not support some fields are ignored in a search.
