Subject RE: Lucene FieldCache memory requirements
Date Tue, 03 Nov 2009 00:59:12 GMT
I just did some tests in a completely new index (Slave), sort by
low-distributed non-tokenized Field (such as Country) takes milliseconds,
but sort (ascending) on tokenized field with heavy distribution took 30
seconds (initially). Second sort (descending) took milliseconds. Generic
query *.*; FieldCache is not used for tokenized fields... how it is sorted
:)
Fortunately, no any OOM.
