An error has occurred trying to run your search. The error has been recorded.
This error can be caused by the search service running out of memory.
This can be verified by gathering a log bundle from the Control Panel and looking at the solr-startup.log file.
Searching for "Caused by" will typically locate the first instance of the problem and the message may appear as follows:
Caused by: java.lang.OutOfMemoryError: Java heap space
It may be necessary to increase the memory assigned to the search service. You are welcome to open a support case to perform this action if you are not comfortable working on the command line or if you do not have root access to your appliance.
