Multiple Property Filters in Enterprise Search
Enterprise Search in Microsoft Office SharePoint Server 2007 keyword syntax supports the use of multiple property filters within the same query. You can use either multiple instances of the same property filter or different property filters.
Using the Same Property Filter
In this scenario, the keyword query is based on a union of the property filters. This is equivalent to the OR operator used in SQL search syntax.
For example, if you specify the following property filters for a keyword query, both the http://marketing and http://customersupport sites are included in the search:
site:http://marketing site:http://customersupport
Using Different Property Filters
In this scenario, the keyword query is based on an intersection of the property filters. This is equivalent to the AND operator used in SQL search syntax.
For example, if you specify the following property filters for a keyword query, all content authored by John Smith from the http://marketing site is included in the search:
site:http://marketing author:"John Smith"
