Only got round to making that change today but it didn't seem to work.
I've added links to the site for the search that returns with any checked, which works, and this one which should return results with all the checkboxes matching.
If you just search without entering anything, it returns all the records with at least one profile keyword.
If you search by checking one checkbox, it returns records with that keyword.
If you search by checking more than one checkbox, it draws a blank.
To test, I've created four test records with the keyword in brackets:
- Transport Interchange (Railway, Light Railway, Metro)
- Railway Scheme (Railway)
- Light Railway Scheme (Light Railway)
- Metro Scheme (Metro)
Checking all three checkboxes Railway, Light Railway and Metro in the checkboxes ANY search correctly returns all four records.
Checking all three checkboxes in the checkboxes ALL search should just return the Transport Interchange scheme, but draws a blank.
Have attached the updated files.
