Thanks for the reply Uwe, we currently can search with MultiReader over all the indexes we have. Now I want to add the faceting search, than I created a categories index for every index I currently have. To accumulate the faceted results now I have a MultiReader pointing all the indexes and I can create a TaxonomyReader for every categories index I have; all the way I see to obtain FacetResults are: 1 - FacetsCollector 2 - a FacetsAccumulator implementation
suppose I use the second option. I should: - search as usual using the MultiReader - than try to collect all the facetresults iterating over my TaxonomyReaders; at every iteration: - I create a FacetsAccumulator using the MultiReader and a TaxonomyReader - I get a list of FacetResult from the accumulator. - as I finish I should in some way merge all the List<FacetResult> I have. I think this solution is not correct because the docsids from the search are pointing the multireader instead the taxonomyreader is pointing to the categories index of a single reader. I neither like to merge all the List of FacetResult I retrieve from the Accumulators. Probably I'm missing something, can somebody clarify to me how I should collect the facets in this case? Nicola.
