Filter by Site Title

[MrWorkingCat]

I need to filter by Site Title, but Site Title property (which maps to ows_SiteName) is not refinable.

Therefore, I mapped RefinableString00 property to ows_SiteName and give it the SiteTitleRefinable alias.

However, I don't have success using the refinable property in the PnP Search Filter web part. I tried with both RefinableString00 and SiteTitleRefinable in the configuration but same thing, the Site Title won't show in the web part.

Is there something else I need to do?

I had success after re-indexing the site.
