Latest versions of Solr have collapsing and expanding plugins,
reranking plugins and post-filters. Some combinations of these seem
like it might be relevant.
And, of course, there is always carrot2 clustering.

Hello,
We need to order solr search results according to specific rules.
I will explain with an example. Let say solr returns 1000 results for query
sport.
These results must be divided into three buckets according to rules that come
from database.
Then one doc must be chosen from each
Hi,
I have some records which include a source_id field which is an integer and
a datetime field. I want the records to be ordered such that the adjacent
records should not have the same source ids. It should perform some sort of
round robin on the records with the source_id as kay and they
Hi,
I am using facets for suggestions. By default facet sort is based only on index
order and count.
Now, in that I have a requirement that based on a value in solr doc ;some
suggestions must be at top and then other.
Example :
doc
iddoc1/id
nameProductInstancename/
://lucene.472066.n3.nabble.com/Autosuggest-Custom-sorting-tp4092980.html

Dear Experts,
I have a requirement for the exact matches and applying alphabetical
sorting thereafter.
To illustrate, the results should be sorted in exact matches and all later
alphabetical.
So, if there are 5 documents as below
Doc1
title: trees
Doc 2
title: plum trees
Doc 3
You may want to look at

While it is not the same requirement, this should give you an idea of how
to do custom sorting.
Thanks

That might be true for sort by 'score' (although even

be best if the first item stayed in place based on

Is custom sorting the best way? or is there something else I'm not

Or you could collapse search results with SOLR-236.
