index appropriate translation of keywords provided by thesaurus

[jodygarnett]

The facets provide the ability to filter documents using the viewers language. However typing this same text does not find the same documents.

Describe the solution you'd like

When indexing the document the "any" field should pull out the appropriate keyword translation as provided by the thesaurus.

Describe alternatives you've considered

Adding every translation into the metadata document does not seem like a good alternative to work around this limitation.

Additional context

This report is based on the use of thesaurus by the luecene index (rather than specific to any schema).

This is just an idea for discussion as I learn how indexing is done; was surprised keyword translations were not respected by text search

Some options we have been investigated to help on this topic:

• INSPIRE themes are mapped to a key https://github.com/geonetwork/core-geonetwork/blob/master/schemas/iso19139/src/main/plugin/iso19139/index-fields/default.xsl#L357-L360 and is used for facets
• Use synonyms at indexing time https://github.com/geonetwork/core-geonetwork/blob/es/web/src/main/webResources/WEB-INF/data/config/index/records.json#L169-L172
• Query expansions at search time is also another one

"any" analyzer is language specific, so we can't really mix keywords in different language in the same field.

Speaking with @josegar74 today I may have a misunderstanding here, sorry I am full of questions while learning :P
