I am able to get all Managed Metadata Columns to show up by adding this to my Filter Category Definition
:
<Category Title="Managed Metadata Columns"
Description="Managed metadata of the documents"
Type="Microsoft.Office.Server.Search.WebControls.TaxonomyFilterGenerator"
MetadataThreshold="3"
NumberOfFiltersToDisplay="3"
MaxNumberOfFilters="20"
ShowMoreLink="True"
MappedProperty="ows_MetadataFacetInfo"
MoreLinkText="show more"
LessLinkText="show fewer" />
The problem is that it shows all Managed Metadata columns in whatever order it wants. Is there a way for me to show only the columns I want and in the order I want in my refinement panel?
