C# application to query Search Server Express 2010

Question

I have been playing around with Search Server Express 2010 and have built up a little windows application in C# to attempt to query the server and return some results. Whenever i attempt to run the query i receive the error "The search request was unable to connect to the Search Service."

My query is below. I have also tried a query of type MSSQLFT.

<QueryPacket xmlns='urn:Microsoft.Search.Query'>
   <Query>
  <SupportedFormats>
     <Format revision='1'> urn:Microsoft.Search.Response.Document:Document</Format>
  </SupportedFormats>
  <Context>
     <QueryText language='en' type='FQL'>
     </QueryText>
  </Context>
  <ResultProvider>FASTSearch</ResultProvider>
  <Range>
     <Count>10</Count>
  </Range>
   </Query>
</QueryPacket>

Neither of my query attempts have worked and both got the same error and nothing i am searching for is assisting with a solution.

I have deliberately broke it in other ways by taking the search server offline, creating an error in the search, etc. and they all give me different errors, so i am thinking the query does actually reach the server ok! (Also i am sure i have permissions correct)

Does anyone have any thoughts? Am i actually even able to search the express version of search server in this manner?

Any assistance would be greatly appreciated.

Cheers

Ok, simple, as it turns out FQL wont work with 2010 express, and is obvious now i think about it (lack of initial research i guess). When i used MSSQLFT query type i accidentally left the

<ResultsProvider>FastSearch</ResultsProvider>

line in there. This was causing the error i was getting.

The query that worked for me was

<QueryPacket xmlns='urn:Microsoft.Search.Query'>
<Query>
<SupportedFormats>
<Format>urn:Microsoft.Search.Response</Format>
</SupportedFormats>
<Context>
<QueryText language='en' type='MSSQLFT'>
SELECT Filename, Title, FileExtension, Path from Scope()
</QueryText>
</Context>
<Range>
<Count>10</Count>
</Range>
</Query>
</QueryPacket>
