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.

Table 9.1. Supported Property Keywords

Keyword	Applies to	Property
album	Music files	Name of album
artist	Music file	Name of artist
author	Document	Author of the document (same as Creator of the Document)
creator	Document	Creator of the document, mapped to dc:creator (for example, creator of PDF files)

Property searches follow the rules mentioned in Section 9.2, “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
