Thanks for the help we are going to try Step 1 and Step 3 as a last option.
I have never done remoting but my basic understanding of it is that Client and the Remote service both have to be .NET(Or same language) in order to work correct. Our test client is php I think.

But I, personally, prefer passing objects(not xml) to clients since that makes coding of the client easier. 2- While iterating through the results, you can directly create the xml string like stringBuilder.Append("<RecipeID>" + recipeID + "</RecipeID>"); without converting to an intermediate structure 3- To get the best performance, you can use "Remoting" and, pass the result directly to the client. You can find an example at http://issues.apache.org/jira/browse/LUCENENET-100 (RemotingTest.rar) 4- >We look at the HitsCollector (maybe not hard enough) do you still have >to convert that to a document in order to get the Values of the >document?

Either way I still have this middle step of taking hits to some other object then convert to xml. We look at the HitsCollector (maybe not hard enough) do you still have to convert that to a document in order to get the Values of the document?

It is better to use the "HitCollector". Second, Why don't you return an array of a custom object and let the WebServer make the serialization for you. Like; [Serializable] public class MyClass { public string RecipeID; public string RecipeTitle; ..... } [WebMethod] Public MyClass[] GetMyClasses() { MyClass[] myclasses = new MyClass[resultCount]; for(int i=0 ; i<resultCount ; i++){ myclasses[i] = new MyClass(); myclasses[i].RecipeID = .... myclasses[i].RecipeTitle = .... ..... } return myclasses; } DIGY -----Original Message----- From: Scott Remiger [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 12, 2008 6:47 PM To: lucene-net-user@incubator.apache.org Subject: Convert Hits to XML We are currently converting the hits to a dataset then onto an XML document which seems inefficient Can someone suggest a better way of doing this?
