Microsoft OLE DB Provider for Microsoft Indexing Service

The Microsoft OLE DB Provider for Microsoft Indexing Service provides programmatic read-only access to file system and Web data indexed by Microsoft Indexing Service. ADO applications can issue SQL queries to retrieve content and file property information.

The provider is free-threaded and unicode enabled.

Connection String Parameters

To connect to this provider, set the Provider= argument to the ConnectionString property to:

MSIDXS

Reading the Provider property will return this string as well.

Typical Connection String

A typical connection string for this provider is:

"Provider=MSIDXS;Data Source=myCatalog;Locale Identifier=nnnn;"

The string consists of these keywords:

Keyword	Description
Provider	Specifies the OLE DB Provider for Microsoft Indexing Service. Typically this is the only keyword specified in the connection string.
Data Source	Specifies the Indexing Service catalog name. If this keyword is not specified, the default system catalog is used.
Locale Identifier	Specifies a unique 32-bit number (for example, 1033) that specifies preferences related to the user's language. These preferences indicate how dates and times are formatted, items are sorted alphabetically, strings are compared, and so on. If this keyword is not specified, the default system locale identifier is used.

Command Text

The Indexing Service SQL query syntax consists of extensions to the SQL-92 SELECT statement and its FROM and WHERE clauses. The results of the query are returned via OLE DB rowsets, which can be consumed by ADO and manipulated as Recordset objects.

You can search for exact words or phrases, or use wildcards to search for patterns or stems of words. The search logic can be based on Boolean decisions, weighted terms, or proximity to other words. You can also search by "free text," which finds matches based on meaning, rather than exact words.

The specific command dialect is fully documented in the Microsoft Indexing Service Reference.

The provider does not accept stored procedure calls or simple table names (for example, the CommandType property will always be adCmdText).

Recordset Behavior

The following tables list the features available with a Recordset object opened with this provider. Only the Static cursor type (adOpenStatic) is available.

For more detailed information about Recordset behavior for your provider configuration, run the Supports method and enumerate the Properties collection of the Recordset to determine whether provider-specific dynamic properties are present.

Availability of standard ADO Recordset properties:

Property	Availability
AbsolutePage	read/write
AbsolutePosition	read/write
ActiveConnection	read-only
BOF	read-only
Bookmark*	read/write
CacheSize	read/write
CursorLocation	always adUseServer
CursorType	always adOpenStatic
