Re: [VuFind-Tech] OR-based filtering

[Demian K. <dem...@vi...>]

Great - glad to hear it's working!  As you say, the display in the sidebar is a bit annoying; another detail we need to address when finding a more generic solution to this problem.

Thank you Demian, this is working. I implemented option 2, which I also preferred.
The only bothering side effect: in facet side bar, where the filters are listed, now stands 'Quelle: Catalog" OR collection:"Website', which I guess can be irritating. But that's finetuning ;-)

Thank you again!
