Recently we have migrated to v7.1. Search was working after migration but suddenly after two days it stopped working. whenever i search with any keyword it is returning no records.
We are using Tomcat 3.6. solr page and admin page loads perfectly. In admin page if search with any keyword, empty xml is returning. I am not sure what went wrong. Can somebody let me know what are all the things i need to verify to fix this issue?
