We are using Magento Enterprise Edition, versio 1.10.1.1. I installed SOLR, which is working fine, and configured Magento to use SOLR. When I push the button "TEST CONNECTION" in the Magento admin, it is succesfull. I do see in the SOLR log files that Magento sends the ping command to SOLR.
Now when I try to actually search something on the website, the search query doesn't reach SOLR. I don't see the select request coming in.
When I do a search query directly to the SOLR engine, I do see the query logged, so it seems to me that SOLR is running fine.
Magento must be falling back to mysql search. But why? How can I debug this? What files are responsible for doing the actual request to SOLR?
All caching has been disabled in Magento.
