Hi,
This week, some devs work together to move forward concretely on
Elasticsearch issues encountered. You will find below a focus on some
points (some are at poc state today) written by Alex and Jajm from
BibLibre. We would be glad to discuss these topics at hackfest in march
and having user feedbacks too :)
#1 Proof of concept for language analyzers
bug 21357 -
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=21357#c32
It's an attempt at having a default ES configuration with stemming,
elision, etc. that works with multi-languages catalogs
You can read the comments and patch for more information.
#2 Compatibilites for tomorrow
Compatibility with latest version of Search::Elasticsearch -
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=24552
Compatibility with Elasticsearch 7.x : Problem: Search::Elasticsearch is
not yet compatible with ES 7.x, so we are stuck with
ES 6.x (unless we use something else...)
#3 Querying Elasticsearch in a better way
POC query_string => boolean query
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=24555
This POC is about replacing the use of full text queries (query_string)
with Boolean queries for biblio search
Advantage:
=> No search craches with special character ( "!", ")" etc...)
=> Separate query context and filter context:
- Search scores are not altered by facets,
- Ability to use range filter (i.e for publication date facet)
Regards,
Claire.
