To be correct, I analyzed FieldCache awhile ago and I believed it never "sizes down"...
/** * Expert: The default cache implementation, storing all values in memory. * A WeakHashMap is used for storage. * * <p>Created: May 19, 2004 4:40:36 PM * * @since lucene 1.4 */ Will it size down? Only if we are not faceting (as in SOLR v.1.3)... And I am still unsure, Document ID vs. Object Pointer. > > I don't understand this: > > so with a ton of docs and a few uniques, you get a temp boost in the RAM > > reqs until it sizes it down. > > Sizes down???
