We are using several taxonomy values that we would like to use in the search refinements. As I understand the crawled property owsmetadatafacetinfo should take care of all taxonomy values and then we can use that for customizing our refinement. The problem is that owsmetadatafacetinfo only seems to include values from Enterprise keywords and not our own created term sets. Have anyone here experienced the same thing?
