Subject Re: any good idea for loading fields into memory?
Date Fri, 22 Jun 2012 00:56:40 GMT
use collector and field cache is a good idea for ranking by certain
field's value.
but I just need to return matched documents' fields. and also field
cache can't store multi-value fields?
I have to store special chars like '\n' to separate them and split
string to string array in runtime.
