🧩 Using the AutoPhrase TokenFilter JAR in Opensolr

The AutoPhrase TokenFilter is a powerful Solr plugin that helps you recognize and index multi-word expressions as single tokens (think: "New York City" as one unit, not three). This can significantly improve the quality of search, autocomplete, and analytics.

⚡️ Is It Enabled by Default?

Not on all Opensolr environments!
If you're trying to use the AutoPhraseTokenFilterFactory and see errors like:

Plugin not found: solr.AutoPhraseTokenFilterFactory

...then the jar isn't active on your server (yet).

🛠️ What To Do?

1. Contact Us
   Simply send us a request and we'll install the AutoPhrase library (or pretty much any other custom Solr plugin) for you.

2. How to Request a Plugin

   • Follow the step-by-step guide: How do I add a lib/jar file?
   • Let us know which version of Solr you're using (the right jar version matters!).
   • Optionally, send the JAR file directly if it's a custom or non-public library.

3. After Installation

   • Once the plugin is in place, add the appropriate <filter class="solr.AutoPhraseTokenFilterFactory" ... /> element to your field type in schema.xml.
   • Reload your core to activate the new filter.
   • Don't forget to update your schema or config if needed—AutoPhrase sometimes requires its own config files or phrase lists.

🚨 Gotchas & Tips

• Version Compatibility: Always use a plugin version that matches your Solr version.
• Security: Opensolr reviews all uploaded JARs for security reasons—public/official plugins are easier/faster to approve!
• Performance: Heavy custom token filters (like AutoPhrase) can impact indexing speed. Test with your real data!
