Metadata Searches

A simple text string can narrow a search to a specific metadata field. This text string can be entered either into the Search box on the home page or in the Search Terms box in the Advanced Search window. This is demonstrated in the following examples:

• To search for the word Chancellor in the image title (slug):

slug=Chancellor

• To search for the word Governor in the slug and the event title:

slug=Chancellor AND title=Chancellor

• Metadata fields can be combined with Boolean operators or wildcards to narrow or widen a search.
  To search for items originated by AP or Canadian Press ( CP) that are not about President Obama, enter the following string:

source=(AP or CP) AND NOT ("President Obama" OR "Barack Obama")

• You can also use "!=" to exclude terms from the metadata field search.

To search for all items that did not arrive at 29 October 2007, 2:11:39pm GMT:

arrivaldatetime!=2007-10-29T14:11:39GMT

To search for items with image ID numbers that begin with X01, but exclude items with fire in the title:

friendlykey=X01* AND title!=fire

• To search using other criteria, see Advanced Searches.

Some commonly used metadata fields to enter in search expressions are:
