Custom Collectors with sorting

I am trying to create custom collectors with custom sort preferences.
eventually I want to use them with the following lucene (low level API) call

 IndexSearcher.search(query,filter,collector)

1. how can we specify the custom sort along with custom collector
(something like TopFieldCollector ?)

2. I am just wondering is there a way to stop collecting after reaching
some criteria/number. For example: a specific query might result in 1000
hits, means the collect method will be called for 1000 times. but if I have
already collected what I need (custom collecting logic) I want to further
hitting/processing the collect method. we can have if conditions within the
collect method, but just wondering is there any way to break the collect
method and stop collecting ?
