For general searches type in one or more words in a field of your choice, e.g. ''Grant'' in the ''Artist/Photographer/Maker'' field.
If you know what you are looking for, narrow down the results using more than one field, e.g. a search for ''Grant'' in the ''Artist/Photographer/Maker'' field and ''bicycle'' in the ''Image Title'' field to find Henry Grant''s ''Two boys riding a bicycle: 1973''.
When searching using more than one word the search brings back the closest matches first.
