Building Search Queries
Last modified: April 15, 2010
Applies to: SharePoint Server 2010
Microsoft SharePoint Server 2010 search supports the following search syntax for building search queries:
Using Keyword syntax, you specify the search terms or property restrictions that are passed directly to the search service. This is the query language that is common to SharePoint Server search and FAST Search Server 2010 for SharePoint, so if you are creating an application that is intended for use with both, you should use Keyword syntax.
This is an extension of SQL syntax for querying databases. It is a structured query language that is not intended to be exposed to end users, but instead to be used for programmatic creation of queries. SQL syntax is supported only with SharePoint Server search.
FAST Query Language (FQL)
FQL is a structured query language that supports advanced query operators. It is not intended to be exposed to end users, but instead to be used for programmatic creation of queries. FQL is supported with only FAST Search Server 2010 for SharePoint.
