CoreResult Webpart fetches 100 refiners eve though MaxnumberofFilters to Display is set to 15.

Question

Hello All,

I have extended the sharepoint core result webpart along with refinement panel and filter generator.

Assume that i have set the maxnumberoffilterstodisplay as 15 and accurracy index is set to 50.

When i only add my extended coreresult webpart or OOB core result webpart on the results page and when i check the query fired in the query logger the query is ok and the refiners fetched against eact category is round about 20-40 refiners.

When i add the OOB  refinement panel webpart of the query logger is the same.

But when i add my extended refinement panel webpart the query logger fetches 100 refiners against each category/ mapped property. Even though the max no of filters to display is set to 15 and accuracy index is set to 50.When i debugged the code under filter generator that i have extended the method

GetRefinement() the refiment data brings the refiners based on accuracy index.

What i want is when i am setting the max no of filters to display as 15 the core result webpart should fetch only 15 refiners not 100.

Hi,

Can you define what you mean by extended the core result web parts and refinement panel?  What changes have you done in particular?  Also for the GetRefinement(),  http://msdn.microsoft.com/en-us/library/microsoft.office.server.search.webcontrols.managedpropertyfiltergenerator.getrefinement.aspx has the following comment:

Remarks

This override calculates the refinement XML that is used to construct the refinement panel.
