Searches contain can contain a combination of 3 sets of data. A list of tags to include, a timespan when the picture was taken and a geographic region in which it was taken.
Each of the sets should be preceded by a word that can, in most cases, be used to tell what kind of data is being specified. Each kind of data can only appear once in each query
Ideally the sentence should look like Pictures <query>, ie. Pictures of dogs from this year
