From 66b76dd33d623cc6165cab8a2a6c8f71f28834e3 Mon Sep 17 00:00:00 2001 From: David Cook Date: Tue, 17 Jun 2014 16:59:32 +1000 Subject: [PATCH] Bug 12430: Use releance ranking without QueryWeightFields The system preference "QueryWeightFields" is mutually exclusive with the system preference "QueryAutoTruncate" and the * truncation modifier, when not using QueryParser. If you use truncation, relevance won't work anymore. (N.B. Relevance doesn't work probably when using QueryParser, but for a very different reason beyond the current scope of this bug.) This patch adds relevance ranking when using truncation (or basically when QueryWeightFields is disabled). _TEST PLAN_ 1) Turn on "QueryWeightFields" and set "QueryAutoTruncate" to auto 2) Turn off "UseQueryParser" 3) Do a keyword search in the OPAC 4) Note that the results are ordered by biblionumber ascending 5) Apply patch 6) Do the same keyword search in the OPAC 7) Note that the results are never ordered differently (presumably in relevance order :P) If you're a stickler, throw in some warns so that you can see what CCL query is being sent to Zebra.
