* move query parser to nom
* add suupport for term grouping
* initial work on infallible parser
* fmt
* add tests and fix minor parsing bugs
* address review comments
* add support for lenient queries in tantivy
* make lenient parser report errors
* allow mixing occur and bool in query
* 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.
* 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.
* Apply suggestions from code review
Applied this command to the code, making it a bit shorter and slightly
more readable.

Quickwit's still heavily relies on generating field names
containing a '.' for nested object, yet allows for
user defined field names to contain a dot.
In order to reuse tantivy query parser, we will end up
using quickwit field names directly into tantivy.
Only '.' will be escaped.
This PR makes minor changes in how tantivy query parser parses
a field name and resolves it to a field.
Some of the new edge case behavior is hacky.
Closes#1355
For date values `chrono` has been replaced with `time`
- The `time` crate is re-exported as `tantivy::time` instead of `tantivy::chrono`.
- The type alias `tantivy::DateTime` has been removed.
- `Value::Date` wraps `time::PrimitiveDateTime` without time zone information.
- Internally date/time values are stored as seconds since UNIX epoch in UTC.
- Converting a `time::OffsetDateTime` to `Value::Date` implicitly converts the value into UTC.
If this is not desired do the time zone conversion yourself and use `time::PrimitiveDateTime`
directly instead.
