Bug 38694: Title boost ES (WIP)
This patch is a rough example, will need tests and maybe an on/off switch
What this patch does is:
1 - Wraps the existing search code in a a "bool" compound query as a "must".
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
4 - Search for: a novel
5 - Apply patch, restart all
6 - Repeat searches, note exact titles are boosted
