Hi Simona, In addition to Ericks' questions:
Are you talking about *search* time or facet-collection time? And how many results are in your result set? I have some experience with collecting facets from large results set, these are typically slow (as they have to retrieve all the relevant facet fields for the facetted doccument). In Lucene 4.8 the RandomSamplingFacetsCollector returned (as per https://issues.apache.org/jira/browse/LUCENE-5476). -Rob On Fri, Feb 26, 2016 at 6:01 AM, Simona Russo <simoru...@gmail.com> wrote: > Hi all, > > we use Lucene *Facet* library version* 4.7.2.* > > We have an *index* with *45 millions *of documents (size about 15 GB) and > a *taxonomy* index with *57* millions of documents (size about 2 GB). > > The total *facet search* time achieve *15 seconds*! > > Is it possible to improve this time?
