I've been investigating this further and I might have found another path to consider.
Would it be possible to create a custom implementation of a SortField, comparable to the RandomSortField, to tackle the problem? I know it is not your standard question but would really appreciate all feedback and suggestions on this because this is the issue that will make or break the acceptance of Solr for this client.

Problem is that they want scores that make results fall in buckets: * Bucket 1: exact match on category (score = 4) * Bucket 2: exact match on name (score = 3) * Bucket 3: partial match on category (score = 2) * Bucket 4: partial match on name (score = 1) First thing we did was develop a custom similarity class that would return the correct score depending on the field and an exact or partial match. The only problem now is that when a document matches on both the category and name the scores are added together. Example: searching for "restaurant" returns documents in the category restaurant that also have the word restaurant in their name and thus get a score of 5 (4+1) but they should only get 4. I assume for this to work we would need to develop a custom Scorer class but we have no clue on how to incorporate this in Solr. Maybe there is even a simpler solution that we don't know about. All suggestions welcome! Thanks, Tom
