Hello All,
I am writing some test cases for a custom-class which
modifies incoming TermQuery and adds some other Terms and returns a
BooleanQuery. As always I have used assertEquals(), which apparently
uses equals() method. I found out that following two queries are
different from each
Thank you, Robert.

Hi Chris,
its only possible with TermRangeQuery/NumericRangeQuery (depending on data
type, corresponding filters can also be used) with both ends null. E.g., Solr
does it that way.

I'm pretty sure that the answer is no and a quick test on a small
index with/without deleted docs showed no difference in the scores,
using 3.0. But that was hardly a rigorous test and I don't know
enough about lucene internals and scoring to give a definitive answer.
Shouldn't be too hard for yo

Yep.

Yes, but that's internal to the skip reader, in both Lucene and Lucy/KS. When

Thanks Ian and Andrzej.
You solved a mystery for us.

Hi,
I use ConstantScoreQuery to find all documents in an index like this:
td = searcher.search(new ConstantScoreQuery(cluCF), null, md, cluSort);
* cluCF is a Filter
* md is int = 999
* cluSort is a Sort
My problem is that I don't always have a filter (cluCF) - so sometimes its
value is 'null'
I think I solved my problem - used MatchAllDocsQuery() - is that the best
solution ?

Yes, the fastest to get *all* documents, as it simply iterates over global
TermDocs(null) without intersecting with a filter.
