Subject RE: facet optimizing
Date Wed, 07 Feb 2007 17:47:47 GMT
Yes most all terms are multi-valued which I can't avoid.
Since the data is coming from a library catalogue I am translating a
subject field to make a subject facet.  That facet alone is the biggest,
hovering near 39k.  If I remove this facet.field things return faster.
So am I to assume that this particular field bogging down operations and
there are no other optimization options besides cutting down this field?

Thanks!

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.
