Sharepoint Web Service search: Specifying number of results returned

I've spent the past few days at the school of hard knocks learning how to search Sharepoint via the http://{servername}/_vti_bin/spsearch.asmx Web Service.

The remaining issue to overcome is that when I perform a search, only the first 10 results are returned. In the returned XML I can see:

<StartAt>1</StartAt>
<Count>10</Count>
<TotalAvailable>42<开发者_运维百科/TotalAvailable>

So I can see that there's a total of 42 total results, but I'm only getting the first 10 return.

The query I'm passing to the Web Service's Query() method is:

<?xml version='1.0' encoding='utf-8' ?><QueryPacket xmlns='urn:Microsoft.Search.Query' Revision='1000'><Query domain='QDomain'><SupportedFormats><Format>urn:Microsoft.Search.Response.Document.Document</Format></SupportedFormats><Context><QueryText language='en-US' type='STRING'>{0}</QueryText></Context></Query></QueryPacket>

How can I modify my query so that it'll return all the results at once?

You need to tell the search how many results you want. You can view the search query schema on MSDN. The relevant section for you is:

<Range>
   <StartAt />
   <Count />
</Range>

You will want something like the following in your Tag

<Range>
   <StartAt>0</StartAt>
   <Count>50</Count>
</Range>

(You probably don't need StartAt as it defaults to 0)

<QueryPacket xmlns="urn:Microsoft.Search.Query" Revision="1000">
      <Query domain="QDomain">
            <SupportedFormats>
                  <Format>urn:Microsoft.Search.Response.Document.Document</Format>
            </SupportedFormats>
            <Range>
                  <Count>MaxNumberGoesHere</Count>
            </Range>
            <Context>
                  <QueryText language="en-US" type="STRING">Maria</QueryText>
            </Context>
      </Query>
</QueryPacket>

I thought I'd tried this before and got an error, hence me asking here. Looks like I must have got the query wrong.
