Troubleshooting Elasticsearch

You might run into some problems running Elasticsearch. Maybe you can find the solution here.

Search works in staff, not in OPAC

Missing suppression-index

Do you have OpacSuppression = Hide? If you do, you also need to have the suppression-index configured. If your Koha instance has gone through some upgrades you might be missing it. Solution:

• Go to "Home › Administration › Search engine configuration (Elasticsearch)"
• Verify that the "suppression" index is missing from the page
• At the bottom of the page, click on "Reset mappings" and confirm
• An index called "suppress" should now show in the list of indexes
• Run a full reindex
• Check if the OPAC search works now
