Michael McCandless commented on LUCENE-8233: -------------------------------------------- +1; this is a simple way to expose soft deletes. I left a few comments on github that Simon already addressed! > Add support for soft deletes to IndexWriter delete accounting > -------------------------------------------------------------- > > Key: LUCENE-8233 > URL: https://issues.apache.org/jira/browse/LUCENE-8233 > Project: Lucene - Core > Issue Type: Improvement > Affects Versions: 7.4, master (8.0) > Reporter: Simon Willnauer > Priority: Major > Fix For: 7.4, master (8.0) > > Attachments: LUCENE-8233.patch, LUCENE-8233.patch, LUCENE-8233.patch > > > This change adds support for soft deletes as a fully supported feature by the > index writer. Soft deletes are accounted for inside the index writer and > therefor also by merge policies. > > This change also adds a SoftDeletesRetentionMergePolicy that allows users to > selectively carry over soft_deleted document across merges for retention > policies. The merge policy selects documents that should be kept around in > the merged segment based on a user provided query. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
