Job board: Faceted Search with "OR" operator, but sort results by most matching facet criterias/term count
Maybe this approach could be an alternative:
Instead of using the tags as facets/filters, I could use them just as search input.
when i'm typing my terms/tags within the search field of an apache-sold-search-page, i'm getting exactly the results sorted by their relevance:

Searching for filters/term instead of using them as real filters

So, maybe I have just to do a small piece of code, that automatically creates a search query based on the clicked term/tags…
