SortedIntDocSet vs HashDocSet

[Marc Sturlese <ma...@gmail.com>]

I use to have a HashDocSet in my own Solr SearchComponent. As HashDocSet is
not used anymore in recent nightlies could I replace it for a
SortedIntDocSet (it didn't exist yet when I create my search component).
Does it make sense?

And another thing... Is there anyway to get a set of internal document id's
sorted by relevance without using a DocList,
I mean, I am doing:

DocList docs = searcher.getDocList(query, filters, sort, 0, maxDocs, flags); 
I do this before executing the normal query, so, I am experiencing some bad
performance. Maybe would help something like:

DocSet docs = searcher.getXXX(query, filters, sort, 0, maxDocs, flags); 
Could this would be faster? Is there any way to do that?

Thanks in advance

Yep.  Make sure the ids you pass are sorted.  I'll update the javadoc
for the class.

Nope... DocSets are either unordered (HashDocSet) or ordered by the
internal docid - there's no way to record a different ordering.
That's what DocList is for.
