v5.13.0

Core

• [fea] Optimized grouping equal positions comparator
• [fea] Added implicit conversion between scalar values and single-value composites
• [fea] Added extendible hashing into hash-indexes. This slightly increases mean insertion time, but makes it much more stable, allowing to avoid huge latency spikes on resizing
• [fea] Improved estimate cost calculation for equal_positions
• [fix] Disallowed creating a sparse index over JSON fields with type 'object'. Previously this behavior could cause a few critical bugs and inconsistent states, and was mostly unusable. This may break compatibility if you have object fields in your sparse indexes
• [fix] Fixed data migration on PK update, when some of the documents are marked as 'deleted'
• [fix] Fixed support for subqueries on the left side of WhereExpressions

Fulltext

• [fea] Reworked initial term variants generation logic. Now the search engine uses variants from previous steps to generate more variants on the current step. For example, variants received from the typos-handling mechanism will be used for stemming, etc.
• [fea] Changed ranking for multiword synonyms. Now rank divides proportionally between all the new terms
• [fea] Changed logic around base ranking config. Now full match will always have the best rank, and all the other base ranks will be proportionally decreased according to the configured values. This may break compatibility in some cases, because from now on there is no way to make full-match rank lower than any other base rank
• [fea] MinRelevancy parameter in config has been deprecated. Added new MinRank parameter, which covers the full ranking range
• [fea] Deprecated FuzzyTextIndex and related configs were removed completely
• [fix] Fixed crash during IS NOT NULL filtering condition and EnablePreselectBeforeFt index option interaction

Vector indexes

• [fea] Added support for multiple vectors in a single field (i.e. array vector indexes)
• [fix] Fixed crash in dequantizing of empty (null) vectors during quantization config update

Reindexer server

• [fea] Added memory limit for max response size (default value is 1 GB) to avoid unexpected OOMs. Limit may be changed via net.max_http_rsp_size yaml-config option, --max-http-rsp CLI flag or RX_MAX_HTTP_RSP Docker env
• [fea] Optimized tags synchronization for Update/Delete queries (new logic allows reducing response sizes by cutting off CJSON tags dictionary)
• [fea] Updated swagger to v5.32

Go connector

• [fea] Bumped dependency versions and updated min Go version (v1.24.0)
• [fea] Optimized some of the CJSON marshaling logic
• [fea] Updated content returned in IsSortable and Conditions fields of the IndexDescription object. Now it corresponds to the actual index capabilities
• [upd] Updated fulltext config structure according to changes in core fulltext indexes

Face

• [fea] Added vertical resize for the JSON preview window on the Index edit page
• [fea] Added new fields to the Vector index settings
