Hi again.

How should faceting behave in case of restricting the results by multiple facets from the same faceting group (i.e. having hte same faceting name)?

Example:
Let's assume that a query in a bibliography results in publications and there appear to be 3 authors in the results:

Results:

The author facets will look like this (ignoring the unrelated collections issue):


What if I first restrict the results on the author facet 'John' and then 'Kim'. Shouldn't the results then only contain 'Publication 1' (like applying filters)? It currently returns Publication 1, 2 and 4, as if selecting the 'Kim' facet had no effect.

How does your domain model look like and the search/faceting code?
Atm, faceting only works on single values fields, due to the use of Lucene's field cache under the hood. This will change though in one of the next releases.

You are right, but this is not causing the problem I'm aiming.

I found this in the source code:

Restricting the results using multiple facets on the same faceting group will thus filter by OR-ing the facets. Is it an idea to have an option for faceting groups to set the default behaviour wrt combining facets?

Some use cases:
When searching for publications, I want the publications where both 'Kim' and 'John' are author
When searching for recipes, I want dishes with both 'tomatoes' and 'eggs'.

And because the faceting implementation uses filtering, the intended publications/dishes with both constraints will not be ranked higher than publications/dishes with only one contraint.
