I’d like to filter some report columns on simple empty/not empty values.
Is there a list of search operators or explanation of filter logic anywhere?
The [Mautic.org](http://Mautic.org) support documentation cryptically refers to such a document, but doesn’t link to it. See:

The search box allows many different search types and follows the same search process and variables as found in all other search layouts. You can learn more about the powerful search options available on the search documentation page.
I'd love to learn more... where? ![:)]( ":)")

Search Operators:
- (plus sign) - Search for the exact string (i.e. if admin, then administrator will not match)
! (exclamation mark) - Not equals string
" " (double quotes) - Search by phrase
( ) (parentheses) - Group expressions together.
OR - By default the expressions will be joined as AND statements. Use the OR operator to change that.
Search commands
is:anonymous
is:unowned
is:mine
email:\*
segment:{segment\_alias}
name:\*
company:\*
