Bug ID: 40853
Summary: ElasticsearchBoostFieldMatch - needs to boost results
more

OS: All
Status: NEW
Severity: normal
Priority: P5 - low

When searching for book titles that may have words in many fields, e.g. 'book
of hope', the boost is not enough, especially when other fields like 'title'
are boosted.
In production with title boost of 32 the general results are getting a score of
~600
The boost query is getting a score of ~10 - not enough to boost past the
general results
We can try a few things:
1 - Use the 'boost' field from 'title-cover' matching in the extra query
2 - Add a system preference (or hard code) to define how much to boost the
additional query by
3 - Try using a boost query rather than a bool query:
