I simulated a hierarchical faceting browsing scheme using facet.prefix. However, it seems there can only be one facet.prefix per field. For OR queries, the browsing scheme requires multiple facet prefixes. For example:
fq=facet1:term1 OR facet1:term2 OR facet1:term3 Something like the above is very powerful. For the hierarchical browsing, at this point what I want is to show the child terms (one level down) of term1, term2 and term3 (but not term4, term5 or term6). Now, if I add a facet.prefix, say "f.facet1.facet.prefix=term1", it would give me all the child terms of term1, but I also want the children of child 2 and child 3. So what I want is to be able to do something like this: "f.facet1.facet.prefix=term1 OR term2 OR term3. Is there a way to accomplish what I'm looking for?
