It applies the same logic on floats as for u64 or i64.
In all case, the idea is (for the inverted index) to coerce number
to their canonical representation, before indexing and before searching.
That way a document with the float 1.0 will be searchable when the user
searches for 1.
Note that contrary to the columnar, we do not attempt to coerce all of the
terms associated to a given json path to a single numerical type.
We simply rely on this "point-wise" canonicalization.
* support ff range queries on json fields
* fix term date truncation
* use inverted index range query for phrase prefix queries
* rename to InvertedIndexRangeQuery
* fix column filter, add mixed column test
The previous way to address the problem was to replace \u{0000}
with 0 in different places.
This logic had several flaws:
Done on the serializer side (like it was for the columnar), there was
a collision problem.
If a document in the segment contained a json field with a \0 and
antoher doc contained the same json field but `0` then we were sending
the same field path twice to the serializer.
Another option would have been to normalizes all values on the writer
side.
This PR simplifies the logic and simply ignore json path containing a
\0, both in the columnar and the inverted index.
Closes#2442
This changes three things:
- Reuse positions_per_path hashmap instead of allocating one per
indexed JSON value
- Try to cast u64 values to i64 to streamline with search behaviour
- Allow top level json values to be of any type, instead of limiting it
to JSON objects. Remove special JSON object handling method.
TODO: We probably should also try to check f64 to i64 and u64 when
indexing, as values may get converted to f64 by the JSON parser
* add fields_metadata to SegmentReader, add columnar docs
* use schema to resolve field, add test
* normalize paths
* merge for FieldsMetadata, add fields_metadata on Index
* Update src/core/segment_reader.rs

* 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
