4.3 Performing a Property Search
By default, the Beagle search tool looks for search terms in the text of
documents and in their metadata. To search for a word in a particular
property, use
property:query.
For example, author:john searches for files that have
“john” listed in the Author property.

Property searches follow the rules mentioned in
Section 4.2, Search Tips.
You can use property searches as an OR query or as an exclusion query,
and phrases can be used as query. For example,
the following line will search for all PDF or HTML documents containing
the word “apple” whose author property contains “john” and whose
title does not contain the word “oranges”:
apple ext:pdf OR ext:html author:john -title:oranges
