"SolrQueryUtil.prepareFacetedSolrQuery" method is used to construct a
SolrQuery. But, it requires additional parameters other than the
original query term.
1) allAvailableFacets: This can be obtained through:
featuredSearch.getAllFacetResults();
2) constraints: This is a map like Map<String, List<Object>>. You should
populate keys of this map with the facet names (i.e directory names).
Corresponding List<Object> should be filled with intended facet values
to filter results. This can be done during the traversal of facet
results obtained in the SearchResult object.
So, the code looks like the one below. I hope it clarifies the usage.
SearchResult allResults = featuredSearch.search("*:*");
Map<String, List<Object> constraints;
//initialize constraints using facet results return in allResults object
SolrQuery query = SolrQueryUtil.prepareFacetedSolrQuery("*:*,
featuredSearch.getAllFacetResults(), constraints);
SearchResult filteredResults = featuredSearch.search(query);
//get the matching documents with provided constraints
List<DocumentResult> documents = filteredResults.getDocuments();

AFAIU, directories correspond with the facet names e.g places as you
mentioned earlier. So, when one goes into the places folder, he will see
the documents having an associated places field. Also, he will see other
folders corresponding to values regarding with places facet. If so, I
also think this is a nice alternative to navigate on documents.

*:* seems to work. Could you please try this one?

I couldn't compile branches as there is a problem when downloading
milton related dependencies.

See above code snippet.
