This way, client code can name the type to e.g. store it inside structs without
resorting to generics and it means that its documentation is part of the crate
documentation generated by `cargo doc`.
* Do some Clippy- and Cargo-related boy-scouting.
* Add BytesFilterCollector to support filtering based on a bytes fast field
This is basically a copy of the existing FilterCollector but modified and
specialised to work on a bytes fast field.
* Changed semantics of filter collectors to consider multi-valued fields
* tokenizer-api: reduce Tokenizer overhead
Previously a new `Token` for each text encountered was created, which
contains `String::with_capacity(200)`
In the new API the token_stream gets mutable access to the tokenizer,
this allows state to be shared (in this PR Token is shared).
Ideally the allocation for the BoxTokenStream would also be removed, but
this may require some lifetime tricks.
* simplify api
* move lowercase and ascii folding buffer to global
* empty Token text as default
* Expose phrase-prefix queries via the built-in query parser
This proposes the less-than-imaginative syntax `field:"phrase ter"*` to
perform a phrase prefix query against `field` using `phrase` and `ter` as the
terms. The aim of this is to make this type of query more discoverable and
simplify manual testing.
I did consider exposing the `max_expansions` parameter similar to how slop is
handled, but I think that this is rather something that should be configured via
the querser parser (similar to `set_field_boost` and `set_field_fuzzy`) as
choosing it requires rather intimiate knowledge of the backing index.
* Prevent construction of zero or one term phrase-prefix queries via the query parser.
* Add example using phrase-prefix search via surface API to improve feature discoverability.
This fixes an issue when min_doc==0 loads terms from the dictionary from
one segment and merges the same term with a subaggregation from another
segment.
Previously the empty structure was not correctly initialized to contain
the subaggregation so the merge was incorrect.
* enable tokenizer on json fields
enable tokenizer on json fields for type text
* Avoid making the tokenizer within the TextAnalyzer pub(crate)
* Moving BoxableTokenizer to tantivy.

* Change in the query grammar.
Quotation mark can now be used for phrase queries.
The delimiter is part of the `UserInputLeaf`.
That information is meant to be used in Quickwit to solve #3364.
This PR also adds support for quotation marks escaping in phrase
queries.
