This particular error message generally appears in the log files as:

`ERROR [SearchServiceImpl] Could not reset lucene directory, assets will not be added to search index: java.io.IOException: Cannot delete /path/to/Cascade CMS/tomcat/indexes/xxxxx`

The underlying problem is typically caused by the O/S account permissions not being set properly on the Cascade CMS installation folder. To correct this issue, the *O/S account used to start Cascade CMS* should be given full privileges (ability to modify, create, delete files) to the Cascade CMS directory along with all of its sub-directories.
