Handling with the faceted search results was changed in MGNLEESOLR-69.
Search results are not persisted in FacetedSolrSearchProvider (is not @SessionScoped anymore) and result are not filled into pager directly.
Instead of it we introduce new FacetedSolrSearchResults object where the results are persisted.
FacetedSolrSearchProvider uses FacetedSolrSearchResults and FacetedSolrPager(which just delegates to FacetedSolrSearchResults#getCount and FacetedSolrSearchResults.getSearchResultItems methods), but SimilarSearchProvider uses just SolrPager where you have to set the results. So we end up with two SolrPager implementations and we are handling with results differently in different providers.
