DA Reporting on Search Terms

In order to report on the search terms used for searches in EV Discovery Accelerator I was using tblIntSearches.XMLText, but the terms are not included in the XML if the search was 'Deleted' status.

The search terms appear to be in  NativeQuery and NativeLegacyQuery, but the format is not XML.

Is there documentation or examples of how to parse the search terms from those fields for reporting?

Or is there another source for this information?
