SOLR Issues: Immense Terms and No Cores in Admin Panel
This post was originally published by myself in Diversus’ internal knowledge base.
Immense Terms Error
When you attempt to build an index within Sitecore, the process may fail and leave you with an error in the logs referring to immense terms.
This happens because the index is not configured to handle content past a certain length.
SOLR is down and admin panel shows that you have no cores, however cores are present on the file system
This can be caused by an incompatibility between SOLR and the version of Java you are using (e.g. Solr version 6.2.1 requires Java version 1.8.0_111).
If you cannot role your Linux server back, then you will need to delete Java and install the correct version as well as fix the reverted permissions on the SOLR directories (use: Sudo chmod –R 777 [file dir]). If that fails, you will have to rebuild your SOLR server.
This can be caused by an Unattended Upgrades package in Linux and It’s a good idea to disable it…
