We are pleased to announce the release of Manticore Search 3.2.2. Downloads are available here and from the Manticore Github page. Docker image is available at Docker Hub.

New features

• Long-awaited autoincrement ID functionality for Real-Time indexes is now available.
• Highlighting on stored fields is now supported by the new HIGHLIGHT() function. HIGHLIGHT() is available in SphinxQL as well as the HTTP API.
• SNIPPET() can use new special function QUERY() for the query parameter. This eliminates the need to duplicate the full-text match string in search statements using SNIPPET() in SELECT clause.
  Highlighting functions receive new parameter ‘field_separator’.

Improvements and changes

• Starting with this version default location of configuration file is /etc/manticoresearch/manticore.conf. In case of upgrading via deb/rpm packaging, the packages will move the existing sphinx.conf to the new location.
• On RHEL/CentOS the service is renamed from searchd to manticore.
• For docker the configuration mount is expected to be /etc/manticoresearch.
• In previous version, querying stored fields from distributed indexes with remote nodes was slow and high-resource demanding. To address this we implemented a lazy fetch of stored fields (they are retrieved only after the final result set is build), bringing the performance similar with queries that don’t carry stored fields.
• String attributes and expressions don’t break anymore the multi-query optimization and parallel FACET optimization. In previous versions, a single attribute introduced in facets would make the aggregations to run sequential, leading to slow faceted searches. Now a faceted search is mostly influenced only by the slowest faceted attribute/expression.
  The gains depend on the composition types of facets, in some cases a faceted search can now be several times faster.
• ICU data file is now shipped in official and icu_data_dir directive is removed. This was due various issues reported between different ICU versions shipped by official OS channels.
• Systemd unit files now ship with ‘Restart=on-failure’ policy, to allow restarting searchd daemon in case of crashed or unwanted shutdowns.
• On RHEL/CentOS 8 Manticore Search is now compiled against mariadb-connector-c-devel and mariadb-connector-c is optional requirement for indexing data from MySQL databases.
  We made this change as mariadb-connector-c is compatible with both MySQL and MariaDB shipped in RHEL/CentOS 8.
