trying to do this as a hook into the SolrIndexSearcher would definitley be
complicated ... laregley because of how matches are collected.
the most straight forward way i can think of to get the data you want is
to consider what you are sorting on, and use that as a range filter, ie...
1) do your search, and filter on id:X
2) look at the values X has in the fields you are sorting on
3) search again, this time filter on those fields, asking for the first N
docs with values greater then whatever id:X has
4) search again, this time reverse your sort, and reverse your filters
(docs with values less hten whatever id:X has) and get the first N docs.
...even if your sort is "score" you can use the frange parser to filter
(not usually recommended for score, but possible)
