Uwe Schindler updated LUCENE-2142: ---------------------------------- Attachment: (was: LUCENE-2142-fix.patch) > FieldCache.getStringIndex should not throw exception if term count exceeds > doc count > ------------------------------------------------------------------------------------ > > Key: LUCENE-2142 > URL: https://issues.apache.org/jira/browse/LUCENE-2142 > Project: Lucene - Java > Issue Type: Bug > Components: Search > Reporter: Michael McCandless > Assignee: Michael McCandless > Priority: Minor > Fix For: 2.9.3, 3.0.2, 3.1, 4.0 > > Attachments: LUCENE-2142-fix-3x.patch, LUCENE-2142-fix-trunk.patch > > > Spinoff of LUCENE-2133/LUCENE-831. > Currently FieldCache cannot handle more than one value per field. > We may someday want to fix that... but until that day: > FieldCache.getStringIndex currently does a simplistic check to try to > catch when you've accidentally allowed more than one term per field, > by testing if the number of unique terms exceeds the number of > documents. > The problem is, this is not a perfect check, in that it allows false > negatives (you could have more than one term per field for some docs > and the check won't catch you). > Further, the exception thrown is the unchecked RuntimeException. > So this means... you could happily think all is good, until some day, > well into production, once you've updated enough docs, suddenly the > check will catch you and throw an unhandled exception, stopping all > searches [that need to sort by this string field] in their tracks. > It's not gracefully degrading. > I think we should simply remove the test, ie, if you have more terms > than docs then the terms simply overwrite one another. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
