From aa85433a14489b3791ae4cd333afbcf76645c291 Mon Sep 17 00:00:00 2001 From: Kevin Carnes Date: Tue, 22 Feb 2022 14:29:15 +0100 Subject: [PATCH] Bug 30152: Elasticsearch - queries with OR don't work with limits When a query with "OR" is combined with a limit in Elasticsearch, the precedence is not preserved and the results are not correct. To test: 1) Set SearchEngine to Elasticsearch 2) Index records in Elasticsearch 3) Do an advanced search 4) Select More options 5) Enter a value for the first Keyword (e.g. Novels) 6) Change "and" before the second Keyword to "or" 7) Enter another value for the second Keyword (e.g. Prose) 8) Limit the search (e.g. Item type Books) 9) Do the search 10) Observe that records with the first keyword are not in the results 11) Apply the patch 12) Repeat the search 13) Observe that results with both keywords are in the results 14) Sign off Sponsored-by: Lund University Library --- Koha/SearchEngine/Elasticsearch/QueryBuilder.pm | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/Koha/SearchEngine/Elasticsearch/QueryBuilder.pm b/Koha/SearchEngine/Elasticsearch/QueryBuilder.pm index 607634c405..269d89c581 100644 --- a/Koha/SearchEngine/Elasticsearch/QueryBuilder.pm +++ b/Koha/SearchEngine/Elasticsearch/QueryBuilder.pm @@ -306,9 +306,7 @@ sub build_query_compat { # them into a structured ES query itself.
