Did you try? The cost of index merging grows when indexes are getting bigger. Try to limit the max document size in a segment by setting setMaxMergeDocs in IndexWriter.
-----Original Message----- From: 治江 王 [mailto:wangzhijiang...@yahoo.com.cn] Sent: Monday, February 16, 2009 1:49 PM To: java-user@lucene.apache.org Subject: the efficiency of creating indexes As i know, the time effciency of creating index is non-linearity with the size of documents. For example, if the size of indexes is 1G, the time cost is 2 hours, If the size of indexes is 10G, the time cost may be 30 hours. Who can tell me what is the reason? Any tips will be appreciated. ___________________________________________________________ 好玩贺卡等你发,邮箱贺卡全新上线! http://card.mail.cn.yahoo.com/ --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
