[ http://issues.apache.org/jira/browse/LUCENE-648?page=comments#action_12427449 ] Jason Polites commented on LUCENE-648: --------------------------------------
I you find that compression level has a meaningful impact (which it may not as suggested), one approach for a low-impact fix would be to allow the end user to specify their own Inflater/Deflater when creating the IndexWriter. If not specified, then behaviour remains as is. If the user specifies a different compression level when retrieving the document, that's their bad luck. > Allow changing of ZIP compression level for compressed fields > ------------------------------------------------------------- > > Key: LUCENE-648 > URL: http://issues.apache.org/jira/browse/LUCENE-648 > Project: Lucene - Java > Issue Type: Improvement > Components: Index > Affects Versions: 2.0.0, 1.9, 2.0.1, 2.1 > Reporter: Michael McCandless > Priority: Minor > > In response to this thread: > http://www.gossamer-threads.com/lists/lucene/java-user/38810 > I think we should allow changing the compression level used in the call to > java.util.zip.Deflator in FieldsWriter.java.

But then every time a document is created > with this field you'd have to call setCompressLevel since Lucene doesn't have > a global Field schema (like Solr). > Any other ideas / prefererences for either of these methods? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
