The User Interface's "Search" box understands simple (no grouping)
boolean expressions of "operator:value" expressions stitched together with
"and" and "or" words, separated by spaces.
Negation is achieved by prepending a minus sign: -is:landscape will match
with pictures of not landscape ratio.
For example
after:"2010-01-01" and before:"2010-03-02T12:33:44" or loc:"Amsterdam"
will return all images having "modtime" between before and after or having
location in Amsterdam.
Usable operators:
after: date format is RFC3339, but can be shortened as required.
before: i.e. 2011-01-01 is Jan 1 of year 2011 and "2011" means the same.
format: file's format (or MIME-type) such as jpg, pdf, tiff.
has:location image has a location (GPSLatitude and GPSLongitude can be
retrieved from the image's EXIF tags).
loc: loc:"new york, new york" or "loc:new york, new york" both work.
If specified, only images having a location near
the specified locations are matched.
Locations are resolved using maps.googleapis.com.
is:image object is an image
is:landscape the image has a landscape aspect
is:pano the image's aspect ratio is over 2 - panorama picture.
is:portrait the image has a portrait aspect.
height: image's height
width: the image's width
