[KinoSearch] Possible Phrase Query Bug

[Matthew O'Connor]

I think I've found a bug with phrase queries.  (The RT queue did not  
look too active so I am mailing it to the list as well).

Here's the reproduction strategy:

1) Create a PolyAnalyzer
2) Create an indexer w/ the above analyzer
3) Add a document w/ a text field of 'zzz xxx yyy zzz'
4) finish() the index
5) create a searcher w/ the above analyzer
6) Do the following phrase search: "yyy zzz"
7) EXPECTED: 1 result.  GOT: 0 results

I have attached a script which demonstrates this issue with  
KinoSearch 0.15. I think the first "zzz" in the body of the text  
field is tripping up the phrase scoring, but that's just a guess.

Is this behavior expected?  If not, is it a known bug?  I looked in  
RT and searched the mailing lists but nothing obviously related came  
back.

Here is my environment:

* OS: Ubuntu Dapper 6.01 GNU/Linux
* CPU: 2.0Ghz quad-core Intel Xeon (64 bit)
* Kernel: 2.6.15-28 (Debian package 2.6.15-28-amd64-xeon)
* Index Filesystem: ext3 (part of a logical volume in LVM)
* /tmp Filesystem: ext3
* KinoSearch: 0.15 (unpatched, from CPAN)
* Perl: 5.8.7 (stock Perl on Ubuntu Dapper 6.01)
* gcc: 4.03
* ld: 2.16.91
