Hi
You should do the following:
TopFieldCollector tfc = TopFieldCollector.create();
FacetsCollector fc = FacetsCollector.create();
searcher.search(query, MultiCollector.wrap(tfc, fc));
Basically IndexSearcher.search(..., Sort) creates TopFieldCollector
internally, so you need to create it outside and wrap both collectors with
MultiCollector.
BTW, you don't need to do new CategoryPath("CATEGORY_PATH", '/'), when the
category does not contain the delimiter.
You can use the vararg constructor which takes the path components
directly, if you have them already.
