Manticore Search 17.5.1

Source: Dev.to

Release Overview

Manticore Search 17.5.1 is a maintenance release that includes bug fixes, minor improvements, and updated recommended library versions. It maintains strong backward compatibility with existing data and queries; see the breaking‑change notes below.

Upgrade considerations

• MCL 10.0.0 – Added support for DROP CACHE. This updates the interface between the daemon and MCL. Older Manticore Search versions don’t support the newer MCL. (Issue #4120)
• Percolate query JSON responses now return _id and _score as numbers instead of strings, matching regular search results. This is a breaking change for clients that relied on the string type. (Issue #4019)

If you follow the official installation guide, the correct library versions will be installed automatically.

Versions

• MCL (Manticore Columnar Library): 10.2.0
• Manticore Buddy: 3.41.0

Highlights

• The updated MCL adds support for Llama, Qwen, Mistral, Gemma, and other models for auto‑embeddings.
• Jieba morphology instances are now shared across tables with the same configuration, greatly reducing memory usage when many tables use Jieba.
• stopwords, wordforms, exceptions, and hitless_words can be set inline in CREATE TABLE, allowing tables to be created without external files.

Notable Fixes

• Fixed JOIN results returning empty or duplicated values when a column was both a string attribute and a stored field; the attribute value is now returned correctly. (Issue #3498)
• Fixed joins on JSON string attributes (e.g., j.s) returning no matches; they now work like joins on plain string attributes. (Issue #2559)
• Fixed highlight() with html_strip_mode=strip corrupting content by decoding entities and altering tags; the original entity form is now preserved. (Issue #1737)
• Fixed ALTER TABLE REBUILD SECONDARY failing with “failed to rename … .tmp.spjidx” when the table had multiple disk chunks. (Issue #3203)
• Fixed distributed queries returning stored fields from the wrong local index when agent tables contain duplicate document IDs. (Issue #4148)
• Fixed table rename breaking tables that use external stopwords, wordforms, or exceptions: ATTACH TABLE now migrates these files properly. (Issue #4176)
• Fixed MATCH with OR over the same phrase in different fields returning matches from other fields. (Issue #4128)
• Fixed ALTER TABLE with table‑level settings failing on tables with auto‑embeddings; serialization now omits knn_dims when model_name is set. (Issue #4131)
• …and many more (47 bug fixes in total). See the full list in the Changelog.
