Searching is largely based on tags, with a number of special keywords available that allow searching based on properties of the images.
Returns images that are tagged with "tagname".
Returns images that are tagged with "tagname" and "othertagname".
Most tags and keywords can be prefaced with a negative sign (-) to indicate that you want to search for images that do not match something.
Returns images that are not tagged with "tagname".
Returns images that are not tagged with "tagname" and "othertagname". This is different than without the negative sign, as images with "tagname" or "othertagname" can still be returned as long as the other one is not present.
Returns images that are tagged with "tagname", but are not tagged with "othertagname".
Wildcard searches are possible as well using * for "any one, more, or none" and ? for "any one".

These fields are supported:
Search for items based on the type of media.
Returns items that contain audio, including videos and audio files.
Returns items that contain video, including animated GIFs.
These search terms depend on the items being scanned for media content. Automatic scanning was implemented in mid-2019, so items uploaded before, or items uploaded on a system without ffmpeg, will require additional scanning before this will work.
