Any suggestions on how to optimize the loading of facets? My index is roughly 35,000 and I am asking solr to return 6 six facet fields on every query. On large result sets with facet params set to false searching is zippy, but when set to true, and facet fields designated, it takes some time to

How many unique values do you have for those 6 fields? And are those fields multiValued or not? Single valued facets are much faster (though not realistic in my domain). Lots of values per field do not good facets make. Erik On Feb 7, 2007, at 11:10 AM, Gunther, Andrew wrote:

This is really interesting. You mean to say i could give the patch a try now i.e. the patch in the blog post :-) I am looking forward to it. I hope it will be standalone i.e. you don't need "the whole nutch" to get a standalone crawler working.. I am not sure if this is how you planned. Regards
