> It's an attempt at having a default ES configuration with stemming,

> Compatibility with Elasticsearch 7.x : Problem: Search::Elasticsearch is

> 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)
