Add field_boosts and fuzzy_fields optional parameters to Index::parse_query

[adamreichold]

An alternative approach to expose this functionality of QueryParser using Python-specific facilities, i.e. optional keyword arguments, instead of exactly mirroring the Rust API and exposing QueryParser as a separate #[pyclass].

Closes #201
Closes #50

@adamreichold @cjrh this works for me, atleast the fuzzy bit. The boosting doesn't seem to work, but perhaps that's a Tantivy issue.

Also, the snippet generator breaks with fuzzy queries. Is that normal?

Also, a huge thank you for getting this done so quickly.

Did you check whether the repr contain the expected boost factors?

I think this is a limitation of how the snippet generator works ATM, i.e. it second guesses the query and finds occurrences instead of being integrated into the query execution. Since it does not consider fuzzy matches, I cannot find them. You probably need to provide a fallback for such queries in your UI.
