Question regarding Windows Desktop Search Queried via AQS

Question

Hi All,

I am having few doubts regarding WDS querying through AQS.

1. Is there a way to get the previewURL so that we can explicitly get the content with that url

2. Can we get results in the form of pagination? (ie from 10-20)

3. Instead of counting in while loop, Do we have any way to get total number of search hits?

Sample code that I am trying for querying WDS:

CSearchManager srchMngr = new CSearchManager();

CSearchCatalogManager srchCatMngr = srchMngr.GetCatalog("SystemIndex");

CSearchQueryHelper srchQueryHelper = srchCatMngr.GetQueryHelper(); srchQueryHelper.QuerySelectColumns = @"System.FileName";

string sqlQuery = srchQueryHelper.GenerateSQLFromUserQuery("hi");

OleDbConnection conn = new OleDbConnection(srchQueryHelper.ConnectionString);

conn.Open(); // Execute the query

OleDbCommand cmd = new OleDbCommand(sqlQuery, conn);

OleDbDataReader srchResult = cmd.ExecuteReader();

while (srchResult.Read()) { . . . . }

It will be really great if I get the solution 

Thanks in advance.
