Difference between KeywordQuery, FullTextQuerySearch type for Object Model and Web service Query
- by Raghu
Initially I believed these 3 to be doing more or less the same thing with just the notation being different. Until recently, when i noticed that their does exists a big difference between the results of the KeyWordQuery/FullTextQuerySearch and Web service Query.
I used both KeywordQuery and FullText method to search of the the value of a customColumn XYZ with value (ASDSADA-21312ASD-ASDASD):-
When I run this query as:- FullTextSqlQuery:-
FullTextSqlQuery myQuery = new FullTextSqlQuery(site);
{
// Construct query text
String queryText = "Select title, path, author, isdocument from scope() where freetext('ASDSADA-21312ASD-ASDASD') ";
myQuery.QueryText = queryText;
myQuery.ResultTypes = ResultType.RelevantResults;
};
// execute the query and load the results into a datatable
ResultTableCollection queryResults = myQuery.Execute();
ResultTable resultTable = queryResults[ResultType.RelevantResults];
// Load table with results
DataTable queryDataTable = new DataTable();
queryDataTable.Load(resultTable, LoadOption.OverwriteChanges);
I get the following result representing the document.
* Title: TestPDF
* path: http://SharepointServer/Shared Documents/Forms/DispForm.aspx?ID=94
* author: null
* isDocument: false
Do note the Path and isDocument fields of the above result.
Web Service Method
Then I tried a Web Service Query method. I used Sharepoint Search Service Tool available at http://sharepointsearchserv.codeplex.com/ and ran the same query i.e. Select title, path, author, isdocument from scope() where freetext('ASDSADA-21312ASD-ASDASD'). This time I got the following results:-
* Title: TestPDF
* path: http://SharepointServer/Shared Documents/TestPDF.pdf
* author: null
* isDocument: true
Again note the path. While the search results from 2nd method are useful as they provide me the file path exactly, I can't seem to understand why is the method 1 not giving me the same results?
Why is there a discrepancy between the two results?
