Elasticsearch status

Elasticsearch status

This page is really just a goal at an overview of where the Elasticsearch in Koha project stands. Anyone should feel free to edit or update

In general Elastic is functional in Koha - once setup and running you can search your catalog and access titles and indexes are updated as items/titles are added.

There are some differences/issues to be aware of, and in reality we need more users/testers to identify differences and so we can decide which are bugs and which should just be considered a feature of ES.

This page should be for the functionality, for installation/dependencies: Elasticsearch installation

Major bugs

Known issues

• Sorting options work only if sorting is enabled in the mappings - we currently ship a standard list of sorting options- this should be based on the mappings
