[xwiki-notifications] [Issue] Commented: (XWATCH-116) Use Lucene as the underlying query engine

[Anca Paula Luca (JIRA)]

    [ http://jira.xwiki.org/jira/browse/XWATCH-116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=28416#action_28416 ] 

Anca Paula Luca commented on XWATCH-116:
----------------------------------------

Actually, since Lucene is not synchronous, i.e. there may be a while from the moment when an item is added in the database and the moment it is retrievable through Lucene, I think the only place it would be appropriate to use Lucene queries is to retrieve the articles list, all other data  (feeds, groups, keywords, etc) needs to be accessible the moment it was created. Actually, if this time is too long, it might be an issue for articles too.
