Subject FST and FieldCache?
Date Thu, 19 May 2011 04:53:10 GMT
I've been pondering how to reduce the size of FieldCache entries when there
are a large number of Strings. I'd like to facet on such a field with Solr
but with less memory.  As I understand it, FSTs are a highly compressed
representation of a set of Strings (among other possibilities).  The
fieldCache would need to point to an FST entry (an "arc"?) using something
small, say an integer.  Is there a way to point to an FST entry with an
integer, and then somehow with relative efficiency construct the String from
the arcs to get there?
