Displaying Managed Property in Search Results - FAST Search for Sharepoint 2010

Question

We are working with Fast Search for Sharepoint 2010 and had some backend setup done with creating some managed properties e.g. BestBetDescription, keywords etc.

From the front-end part we are creating an application what will fetch all these properties and display in a grid.

However while querying the backend we are NOT getting these managed properties (BestBetDescription) along with other properties such as Title, URL etc.

Following is my source code:

settingsProxy = SPFarm.Local.ServiceProxies.GetValue<SearchQueryAndSiteSettingsServiceProxy>();
searchProxy = settingsProxy.ApplicationProxies.GetValue<SearchServiceApplicationProxy>("FAST Query SSA");
keywordQuery = new KeywordQuery(searchProxy);
keywordQuery.EnableFQL = true;
keywordQuery.QueryText = p;
keywordQuery.ResultsProvider = SearchProvider.FASTSearch;
keywordQuery.ResultTypes = ResultType.RelevantResults;
ResultTableCollection resultsTableCollection = keywordQuery.Execute();
ResultTable searchResultsTable = resultsTableCollection[ResultType.RelevantResults];
DataTable resultsDataTable = new DataTable();
resultsDataTable.TableName = "Results";
resultsDataTable.Load(searchResultsTable, LoadOption.OverwriteChanges);
return resultsDataTable;

The results are returned and I cannot see the Managed properties which we create in the resultDataTable.

Is there any property I missed or is this a backend issue ?

Thanks.

Answer 1

I was missing a property KeywordQuery.SelectProperties

So the code looks something like this

String[] arrSearchProperties = new String[] { "Title", "body", "url" };
KeywordQuery.SelectProperties(arrSearchProperties);

This will fetch you all the Managed Properties defined by you.
