PQF search X-Git-Tag: YAZ.2.1.30~18 X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=54d355d7afb0060f176c956abcf7ad7b895211fc;p=yaz-moved-to-github.git Changed the way PQF queries are encoded in SRU GET/POST. PQF search before: x-pquery=pqf . PQF search now: query=pqf&x-querytype=pqf . This makes the SRU request more conformant because the required query parameter is always present. PQF scan before: x-pScanClause=pqf . PQF scan now: scanClause=pqf&x-querytype=pqf . --- diff --git a/NEWS b/NEWS index 200dfc4..2e1a72e 100644 --- a/NEWS +++ b/NEWS @@ -1,3 +1,9 @@ +Changed the way PQF queries are encoded in SRU GET/POST.
