I was wondering if it was possible to search for multiple tags; there have been several previous posts about this capability and kuemerle5 has raised a development / feature request.
However having followed this through and looked at the code, the capability is already in the system through the mySQL Ful text search function that is utilised. For instance to search for photos with both the tags "red" and "box", you need to enter a search string "+red +box". The space after the d of red is vital. To search for red tags but not boxes use "+red -box".
A note in the User Guide or FAQs would help newbies out.
