Well, it's probably not quite that bad... For string sorting, a FieldCache.StringIndex is used. It contains a sorted String[num_unique_terms_in_field], and an int[maxDoc] So if 10 documents share a large string field value, that value will only be in the fieldCache once. If you are just using an IndexSearcher (no multisearchers), then the String[] isn't strictly needed... only the ordering (the int[]) is needed from the StringIndex. One option is to create your own FieldCache that doesn't create/store that String[]. -Yonik http://incubator.apache.org/solr Solr, The Open Source Lucene Search Server --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
