🏗️ Using Custom JAR Libraries in Opensolr

Need a special Solr plugin or custom filter?
No problem! Opensolr supports custom JAR libraries—so you can fine-tune your search platform with advanced features.


🚚 How to Install a Custom JAR Library

  1. Send Us Your JAR
    Email your custom JAR file (or a link to the official plugin page where binaries are already compiled) to [email protected].

  2. Include This Info

  3. Your Opensolr Registration Email Address
  4. The Opensolr Index Name (where you want the plugin installed)

  5. Installation Timeline

  6. Most installations are done within a couple of hours (we say “up to 24 hours” to cover rare edge cases and to sound like responsible adults).
  7. If the plugin is fully compatible with your Solr version, it’s usually lightning fast!

🛡️ Pro Tips for Success

  • Send the JAR File Itself
    Don’t just send the source code. We need the compiled .jar binary!
  • Official Sources Are Best
    For security and speed, send links to official or reputable plugin pages.
  • Version Match Matters
    Double-check that your JAR matches your Solr version—otherwise it might throw errors (or, even worse, not work at all).

🔄 After Installation

Once we’ve installed the plugin: - Update your schema.xml or solrconfig.xml to use your new library (we can help with this if needed). - Reload your Solr core to activate the changes. - Test your configuration—give it a spin!
