Dear Wiki user,

The "SolrCaching" page has been changed by YonikSeeley.
The comment on this change is: hash doc set not relevant to 1.4.


  == The hashDocSet Max Size ==
+ <!> This is not relevant to [[Solr1.4]] and later, which as a more efficient, general
purpose small set implementation that currently has no external configuration.
  The hashDocSet is an optimization that enables an int hash representation for filters (docSets)
when the number of items in the set is less than maxSize.  For smaller sets, this representation
is more memory efficient, more efficient to iterate, and faster to take intersections.
