Hi Yonik, Thanks for the reply.
I have around 200M documents in index. The field I'm sorting on is a date string (containing date and time in dd-mmm-yyyy hh:mm:yy format) and the field is part of the search criteria. Also please note that the number of documents returned by the search criteria is much less than 200M. In fact even in case of 0 hit I found jvm out of memory exception.

Sorting in lucene and solr uninverts the field and creates a FieldCache entry the first time the sort is used. How many documents are in your index, and what is the type of the field you are sorting on? -Yonik **************** CAUTION - Disclaimer ***************** This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).
