feat: handling synonyms and text fields more efficiently

alexgarel commented 3 months ago

Using synonyms capabilities of ES to avoid storing taxonomies fields in the index
Better handling of full text queries that support them within any expression
make boost_phrase a separate parameter
Raise errors if the query is not well understood or do not pass some sanity checks
Use main translation of taxonomy for facets values (instead of a random synonym)
Better handling of global config to avoid treacherous patterns
Unify parameters for Get and Post (better use of pydantic)
Error on extraneous search parameters to avoid hard to debug issues with typos

Part of: #193

@raphael0202 revealed some pending issues:

[x] make labels:"fair-trade" work (it does not work because of the "-" being splet in two words)
[x] make labels:"appellation d'origine protégée" work (it does not work because of apostrophe

It might be a change in analyzer and/or synonyms file. Apart from adding new test in test_search.py, I need to add a test on ES analysis, as it will help document behaviour.
