lukaskolafa opened a new issue #247:
URL: https://github.com/apache/lucenenet/issues/247


   Hello, I am scratching my head, what is the purpose of the parameter `n` in the method `FacetsCollector.Search(..., n, ...)`. From various posts out there in internet (including java questions), it looks like the argument limits the results for Facets which deliver n+ hits. But this is not the behavior I observe, in my case, whatever number I use, the results is the same. Here is my code I use, based on the sample I found [here](https://github.com/apache/lucenenet/blob/master/src/Lucene.Net.Demo/Facet/SimpleFacetsExample.cs). 
   
   One suspicious place in the code is that the return value of the `Search` method is not used. But this is the same case as in the referenced github sample.
   
   any help is appreciated.. thank you!
   
   ```
               BooleanQuery searchQuery = this.CreateLuceneSearchQuery(performCourseSearchRequest);
   
               var facetsCollector = new FacetsCollector();
   
               /*
                * This value should theoretically limit the result to return only facets with at least N results (hits). For some reason this
                * seems not being working and regardless what the number is, it returns always everything.
                */
               const int NumHitsLimit = 1;
   
               // Return value is not used, the searchQuery affects the referenced facetsCollector
               _ = FacetsCollector.Search(catalogSearchContainer.GetCurrentIndexSearcher(), searchQuery, NumHitsLimit, facetsCollector);
   
               var facets = new FastTaxonomyFacetCounts(catalogSearchContainer.GetCurrentTaxonomyReader(), FacetsConfigFactory.CreateFacetsConfig(), facetsCollector);
   
               foreach (var facetField in facetFields)
               {
                   FacetResult facetResult = facets.GetTopChildren(MaxFacetChildrenHits, facetField);
   
                   if (facetResult != null)
                   {
                       facetResults.Add(new FacetItem(facetResult));
                   }
               }
   
               return facetResults;
   ```
