Enterprise Search Property Filters

By using property filters, you can narrow the focus of the keyword search based on the following:

For information about managed properties, see Managing Metadata. For information about search scopes, see Working with Search Scopes.

<property name>:<value>
<scope name>:<value>
<collapsed results type>:<value>

Remarks

Keyword property filters have no maximum length; however, the full length of the keyword query should be less than 1024 characters.

You can specify a prefix, which includes part of a word, from the beginning of the word, for keyword property filter queries.

Keyword syntax supports querying on the full set of managed properties for any properties of a string or numeric type.
