📄 Troubleshooting Tika Extractor Errors with Opensolr

So, your Tika Extractor is throwing a tantrum (a.k.a. errors) in Drupal or another application? Fear not! Here’s what you can do to get your content extraction back on track—without losing your mind (or your data).

1. Try a Different Solr Version

Before you deep-dive into endless logs, try creating a new Opensolr Index in an environment using Solr Version 9, or even 7, 6, or 5.
Avoid Solr 8.x – it has some famous-for-all-the-wrong-reasons Jetty issues that often cause Tika-related problems.

👉 Create a new Opensolr Index

2. Make Sure Tika Is Enabled in Your Region

If you suspect Tika’s not even present (it happens!), Contact Opensolr Support and let us know.
We’ll happily enable Tika for your index and region if it’s not already there.

3. Confirm Your solrconfig.xml Setup

Check that your solrconfig.xml has the proper Tika Extraction RequestHandler defined:

<requestHandler name="/extract/tika" class="org.apache.solr.handler.extraction.ExtractingRequestHandler" startup="lazy">
    <lst name="defaults">
    </lst>
    <!-- This path only extracts - never updates -->
    <lst name="invariants">
        <bool name="extractOnly">true</bool>
    </lst>
</requestHandler>

This makes sure Tika extraction is only extracting—no accidental document updates sneaking in.
