Below is a little self-contained test program. You may recognise some
of the code.
Here's the output from a couple of runs using lucene 4.4.0.
$ java ian.G1 "Dremel is a scalable, interactive ad-hoc query system"
"interactive ad-hoc"
term=interactive
term=ad-hoc
+content:"interactive" +content:"ad-hoc": totalHits=1
$ java ian.G1 "Dremel is a scalable, interactive ad-hoc query system"
"interactive adhoc"
term=interactive
+content:"interactive": totalHits=1
All looks OK to me. Maybe you can make it fail, or use it to help fix
your problem.
