v5.14.0

Core

• [fea] Improved heuristic for scan order selection when a multi-condition query requires sorting but background index optimization has not run (typical for mixed read/write workloads)
• [fea] Improved planner logic for scan order selection when explicit sorting is not required
• [fea] Replaced hash value mixing logic for composite indexes. The new implementation significantly reduces collision probability on insert into hash-composite indexes (mean insert time reduced by 5-20% depending on composite value composition)
• [fix] Fixed checksum mismatch error when loading data from disk after removing a UUID index

Fulltext

• [fea] Added term splitting (handles missing whitespace). For example, query leonardodicaprio can now match a document with Leonardo Di'Caprio. See EnableTermsSplit and SplitProc in the fulltext index config
• [fix] Fixed search for terms ending with a dot-character (.) — previously this conflicted with incorrect keyboard layout search
• [fix] Fixed EnableTranslit and EnableKbLayout flag behavior — since v5.12.0, transliteration and wrong keyboard layout search could not be disabled by setting these flags to False

Vector indexes

• [fea] Added support for vector arrays in auto-embedding on insert. Auto-embedding can now be used for data chunking on the embedding service side

Reindexer server

• [fea] Added HTTP endpoints POST /api/v1/query/convert/dsl and POST /api/v1/query/convert/sql to convert and prettify SQL/DSL queries
• [fea] HTTP endpoint GET /db/{database}/suggest now returns parsing error details
• [fix] Fixed --max-http-req=0 flag behavior. A zero value now sets the maximum request size to unlimited

Reindexer tool

• [fea] Added dry-run mode to validate a dump file without applying it. More on validation
• [fea] Added progress bar display while applying a dump

Go connector

• [fea] Optimized CJSON encoding/decoding
• [fea] Optimized Query building process

Build/Deploy

• [fea] Added pre-built packages for Fedora 43/44
• [upd] Deprecated Fedora 41/42 pre-built packages

Face

• [fea] Added queued_namespace_syncs column to Statistics table
• [fea] Implemented Backend-side Prettify for Frontend: the new prettify version not only formats the query but also places parentheses according to actual operator precedence
• [fea] Improved error interpretation for SQL editor
• [fea] Added EnableTermsSplit and SplitProc to Fulltext config
• [fix] Fixed default value for UUID field
