Thanks, Peter! I'll try collapsing today.
Example (sorry if table unformated): id | type | prop_1 | .... | prop_N | folderId ________________________________________ 0 | folder | | | | 1 | file | val1 | | valN1 | 0 2 | file | val3 | | valN2 | 0 3 | file | val1 | | valN3 | 0 4 | folder | | | | 5 | folder | | | | 6 | file | val3 | | valN7 | 6 7 | file | val4 | | valN8 | 6 8 | folder | | | | 9 | file | val2 | | valN3 | 8 10| file | val1 | | valN2 | 8 11| file | val2 | | valN5 | 8 12| folder | | | | I need to select always *one* file per folder or select *only* folders than contains matched files (without files). Query: prop_1:val1 OR prop_2:val2 I need results (document ids): 1, 9 or 0, 8 2010/7/23 Peter Karich <peat...@yahoo.de> > Hi Pavel! > > The patch can be applied to 1.4. > The performance is ok, but for some situations it could be worse than > without the patch. > For us it works good, but others reported some exceptions > (see the patch site: https://issues.apache.org/jira/browse/SOLR-236) > > > I need only to delete duplicates > > Could you give us an example what you exactly need? > (Maybe you could index each master document of the 'unique' documents > with an extra field and query for that field?) > > Regards, > Peter. > > -- Pavel Minchenkov
