Description
|
||
|
|
===========
|
||
|
|
The AdvQuery sample is an example command-line application written in C++
|
||
|
|
that executes a query using the OLE DB Provider interfaces such as ICommand
|
||
|
|
and ICommandTree. It shows how to specify a catalog, machine name, and
|
||
|
|
scope. It can also display the OLE DB command tree for the query.

User's Guide
|
||
|
|
============
|
||
|
|
* To build the sample
|
||
|
|
1. Set the Lib environment variable to "D:\mssdk\Lib;%Lib%" and the
|
||
|
|
Include environment variable to "D:\mssdk\Include;%Include%",
|
||
|
|
where D: is the drive on which you installed the Platform SDK.
|
||
|
|
2. Correctly set the CPU environment variable to, for example, "i386".
|
||
|
|
3. Open a command window and change the directory to the source path
|
||
|
|
of the sample.
|
||
|
|
4. Build the sample by entering, at the command-line prompt, "nmake".
|
||
|
|
|
||
|
|
* To issue a query to Indexing Service using the sample
|
||
|
|
1. Open a command window and change the directory to the path of the
|
||
|
|
built sample.
|
||
|
|
2. Formulate a query that you know will succeed. You need to know the
|
||
|
|
machine, catalog, scope, and query text.
|
||
|
|
3. Submit the query by entering, at the command-line prompt,
|
||
|
|
|
||
|
|
advquery <query> [/c:<catalog>] [/m:<machine>] [/s:<scope>] [/d]
|
||
|
|
|
||
|
|
where
|
||
|
|
|
||
|
|
<query> is a query in the Indexing Service Query Language
|
||
|
|
<catalog> is the name of the catalog (default is "system")
|
||
|
|
<machine> is the name of the machine (default is ".")
|
||
|
|
<scope> is the root path (default is entire catalog)
|
||
|
|
/d displays the DBCOMMANDTREE (default is don't display)
|
||
|
|
|
||
|
|
|
||
|
|
Programming Notes
|
||
|
|
=================
|
||
|
|
The sample prints the rank, size, and path of each file that matches the
|
||
|
|
query. The query results are sorted by rank (how well the file matches
|
||
|
|
the query).
|
||
|
|
|
||
|
|
This example is more complex than the Simple (QSample) sample because it
|
||
|
|
creates a command tree and use the low-level ICommandTree interface
|
||
|
|
instead of using the OLE DB Helper functions CICreateCommand and
|
||
|
|
CITextToFullTree.
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
The <query> parameter can be a word or a phrase. Files that contain the
|
||
|
|
word or phrase are listed in the result. To include a space in a query,
|
||
|
|
enclose the query in quotes.
|
||
|
|
|
||
|
|
The <catalog> parameter is the name of the catalog to be queried. The
|
||
|
|
default is "system", which is the default catalog installed with Windows
|
||
|
|
2000. Additional catalogs can be created with the Indexing Service
|
||
|
|
snap-in of the Microsoft Management Console (MMC).
|
||
|
|
|
||
|
|
The <machine> parameter is the name of the machine on which the query
|
||
|
|
will be executed. The default is ".", which is the local machine.
|
||
|
|
Machine names should not be preceeded with two backslashes.
|
||
|
|
|
||
|
|
The <scope> parameter is the file path under which files must exist
|
||
|
|
to be included in the results. The default is "\", which includes all
|
||
|
|
scopes in the catalog.
|
||
|
|
|
||
|
|
The "/d" parameter displays the DBCOMMANDTREE structure built to execute
|
||
|
|
the query.
|
||
|
|
|
||
|
|
Examples
|

|
|
--------

||
|
|
|
||
|
|
advquery foo /m:SERVERNAME
|
||
