A 404 Error means that the browser was able to communicate with Solr, but Solr could not find what was requested.
In the case of a SearchStax Solr deployment, the 404 Error usually means that you sent a query to a collection that did not exist. In one case, someone sent in queries that demanded &rows=100000000… one hundred million rows of output. Solr could not allocate that much space and replied with a 404 error.
Possible reasons for encountering a Solr 404 error include:
- Incorrect URL: You might have entered an incorrect URL or endpoint when trying to access a specific Solr core or resource.
- Core or Collection Name: In Solr, collections or cores represent different indexes or data sets. If you specify a core or collection name that doesn’t exist, you’ll get a 404 error.
- Misconfigured Solr: If your Solr server is not properly configured, it may not recognize the requested URL, leading to a 404 error.
To resolve a Solr 404 error, you should:
- Double-check the URL you are using to access Solr and ensure it is correct.
- Verify that the Solr core or collection you are trying to access exists.
- Ensure that your Solr server is properly configured and running.
