Search for Managed property (Managed Metadata) no results

Question

I´ve defined a web site column of the type "Managed Metadata". The corresponding crawled property is mapped to a managed property.
When I use this property within a Highlighted Content Webpart I get no results. When using the automatic generated managed property there is only one document in the resultset.

I expected 2 results

Several redefines and reindexes of the library and websites didn´t change the behaviour.
Do you have any hints to solve the problem?

Hi @Peter Schneider ,

I noticed that you used ows_taxId_informationstyp when setting the managed property. ows_taxId type property is automatically generated but is not associated to any crawled property. We usually don't use it in web part. You can remove this mapping to see if filtering works. Also, if you're still having issues with managed properties you've created yourself, you can try editing to use OOTB's managed properties and map ows_informationstyp to crawled properties, which usually causes no other issues.

Here is a specific case for your reference: Unable to use the new "Highlighted content" modern web part to show documents that are linked to certain terms inside our term set

Answer 2

The ows_taxId_informationstyp property seemed to be the problem. After removing it from the managed property the results are shown as expected.
