From: Adam Dickmeiss Date: Thu, 7 Jun 2012 12:51:36 +0000 (+0200) Subject: Position modifier for sort prevents local sort X-Git-Tag: v1.6.15~15^2~1 X-Git-Url: http://sru.miketaylor.org.uk/?a=commitdiff_plain;h=eb673212c641c36afba4cd502e283247de52a015;p=pazpar2-moved-to-github.git Position modifier for sort prevents local sort Sort spec may be suffixed with p, for example "title:0p" which sorts by position locally (ie no sort), but by title natively (if sortmap is given). This allows getting sorted records from a database that Pazpar2 does not resort. --- diff --git a/src/client.c b/src/client.c index 0ded33b..e6ddc66 100644 --- a/src/client.c +++ b/src/client.c @@ -1290,8 +1290,7 @@ int client_parse_query(struct client *cl, const char *query, if (!se->relevance) { // Initialize relevance structure with query terms - se->relevance = relevance_create_ccl( - se->service->charsets, se->nmem, cn);
