SolrQuery::collapse — Colapsa o conjunto de resultados para um único documento por grupo
Colapsa o conjunto de resultados para um único documento por grupo antes de encaminhar o conjunto de resultados para o restante dos componentes de pesquisa.
Portanto, todos os componentes posteriores (facetamento, realce, etc...) funcionarão com o conjunto de resultados recolhido.
