Not necessarily interested in grouping by mimetype (that's an analysis issue). I simply used videos and images as an example. I'm not sure what you mean by fuzzy grouping. But my goal is to have collapse be more selective somehow on what gets grouped. As a more specific example, I have a field called 'type', with the following possible field values: Type ------ image video webpage Basically I want to be able to collapse all the images into a single result so that they don't fill up the first page of the results. This is not possible with the current grouping implementation because if you call group.field=type, it'll group everything. I do not want to collapse videos or webpages, only images. I've attached a screenshot of google's srp to help explain what I mean. http://lucene.472066.n3.nabble.com/file/n3471548/Screen_Shot_2011-11-01_at_11.52.04_AM.png Hopefully that makes more sense. If it's still not clear I can email you privately. -- View this message in context: http://lucene.472066.n3.nabble.com/Selective-Result-Grouping-tp3391538p3471548.html Sent from the Solr - User mailing list archive at Nabble.com.
