use usize in bitpacker to enable larger columns in the columnar store
Godbolt comparison with u32 vs u64 for get access: https://godbolt.org/z/cjf7nenYP
Add a mini-tool to inspect columnar files created by tantivy. (very basic functionality which can be extended later)
* add RegexPhraseQuery
RegexPhraseQuery supports phrase queries with regex. It supports regex
and wildcards. E.g. a query with wildcards:
"b* b* wolf" matches "big bad wolf"
Slop is supported as well:
"b* wolf"~2 matches "big bad wolf"
Regex queries may match a lot of terms where we still need to
keep track which term hit to load the positions.
The phrase query algorithm groups terms by their frequency
together in the union to prefilter groups early.
This PR comes with some new datastructures:
SimpleUnion - A union docset for a list of docsets. It doesn't do any
caching and is therefore well suited for datasets with lots of skipping.
(phrase search, but intersections in general)
LoadedPostings - Like SegmentPostings, but all docs and positions are loaded in
memory. SegmentPostings uses 1840 bytes per instance with its caches,
which is equivalent to 460 docids.
LoadedPostings is used for terms which have less than 100 docs.
LoadedPostings is only used to reduce memory consumption.
BitSetPostingUnion - Creates a `Posting` that uses the bitset for docid
hits and the docsets for positions. The BitSet is the precalculated
union of the docsets
In the RegexPhraseQuery there is a size limit of 512 docsets per PreAggregatedUnion,
before creating a new one.
Renamed Union to BufferedUnionScorer
Added proptests to test different union types.
* cleanup
* use Box instead of Vec
* use RefCell instead of term_freq(&mut)
* remove wildcard mode
* move RefCell to outer
* clippy
* store DateTime as nanoseconds in doc store
The doc store DateTime was truncated to microseconds previously. This
removes this truncation, while still keeping backwards compatibility.
This is done by adding the trait `ConfigurableBinarySerializable`, which
works like `BinarySerializable`, but with a config that allows de/serialize
as different date time precision currently.
bump version format to 7.
add compat test to check the date time truncation.
* remove configurable binary serialize, add enum for doc store version
* test doc store version ord
* change AggregationLimits behavior
This fixes an issue encountered with the current behaviour of
AggregationLimits.
Previously we had AggregationLimits and RessourceLimitGuard, which both
track the memory, but only RessourceLimitGuard released memory when
dropped, while AggregationLimits did not.
This PR changes AggregationLimits to be a guard itself and removes the
RessourceLimitGuard.
* rename AggregationLimits to AggregationLimitsGuard
* Fix: Improve collapse_overlapped_ranges function
- Refactor into separate sort_and_deduplicate_ranges and merge_overlapping_ranges functions
- Enhance sorting to consider both start and end of ranges
- Optimize merging logic to handle adjacent ranges
- Add comprehensive examples in function documentation
- Ensure proper handling of duplicate and unsorted input ranges
- Improve overall efficiency and readability of range collapsing algorithm
* move debug_assert

(a OR b) OR (c OR d) can be simplified to (a OR b OR c OR d)
(a AND b) AND (c AND d) can be simplified to (a AND b AND c AND d)
This directly affects how queries are executed
remove unused SumWithCoordsCombiner
the number of fields is unused and private
* 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
* add Key::I64 and Key::U64 variants in aggregation
Currently all `Key` numerical values are returned as f64. This causes problems in some
cases with the precision and the way f64 is serialized.
This PR adds `Key::I64` and `Key::U64` variants and uses them in the term
aggregation.
* add clarification comment
avoid single segments lists without deletes as merge candidates, as they will be moved
to a merge operation and filtered for merging in the next
consider_merge_options call. In rare cases this may end up in a endless
merge loop where only single segments where nothing is to be done are
merged.
* add support for str fast field range query
Add support for range queries on fast fields, by converting term bounds to
term ordinals bounds.

* extend tests, rename
* update comment
* update comment
As preparation of #2023 and #1709
* Use Term to pass parameters
* merge u64 and ip fast field range query
Side note: I did not rename range_query_u64_fastfield, because then git can't track the changes.
