Long-awaited autoincrement ID functionality for Real-Time indexes is now available.
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
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.
