[jira] [Commented] (OAK-3973) There should be a way to get filtered suggestions based on some path

["Vikas Saurabh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-3973?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15130147#comment-15130147 ] 

Vikas Saurabh commented on OAK-3973:
------------------------------------

One of the possible approach is to allow a query of the form:
{noformat}
SELCT rep:suggest() from [someType] where *ISDESCENDANTNODE([/filter/root/path])* AND SUGGEST('sugg') //similarly for xpath
{noformat}

Note, the result rows would still have {{jcr:path=="/"}} (though they need to get {{null}} - OAK-3507) while internally what we want is to filter the results according to this path. [~tmueller], do you think this is acceptable query form for indicate that we want suggestion from under that sub-tree? Any other suggestions?

> Currently, suggestions are indexed at index level - so, when querying for suggestions, the result incorporates all documents indexed by that document.
> So, this doesn't allow filtering suggestions for a subset of indexed document - at least we should be able to get filtered suggestion based on a root path.
> This seems very similar to a functionality provided by lucene vide LUCENE-5528 which was fixed in lucene 4.8. Since oak is still on 4.7, so, we can't exploit that feature.
