This should not affect relevancy or results of the existing searches. 2 - Before we clean/truncate terms, loop through the passed in search terms and indexes to build a new 'should' query, using the 'match' on the specified index/field that is added to the 'bool' query from above. This means that if a result from the original query is also returned here, that item will be boosted in the result. For searches on 'keyword' or 'title', or if no index is set, we use 'title-cover' as the most narrow form of title This query isn't going to help when users enter CCL (i.e. ti:To die for) and it won't boost titles from 505, series, etc when doing a general search. Nor will it have a detrimental effect, it will only boost field matches To test: 1 - Add a record with 245 $a novel 2 - Add a record with 245 $a A novel : $b about things / $c by me 3 - Search for: novel - Above records are returned lower in the list (results #6 and #14 for me) 4 - Search for: a novel - Above records are returned lower in the list (results #6 and #14 for me) 5 - Apply patch, restart all, enable ESBoostFieldMatch option 6 - Repeat searches, note exact titles are boosted - For 'novel' record from #1 is #1 result and other is second - For 'a novel' record form #2 is #1 result and other is third 7 - Disable the new pref and repeat steps 3 and 4 and get results as before patch 8 - Experiment with other searches, turning pref on and off to verify relevant titles are boosted when enabled 9 - Search results when disabled should return as before the patch Signed-off-by: Matthias Meusburger <[email protected]> -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list [email protected] https://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
