This issue should be resolved in the sortfieldwriter branch. The following two commits are
the crucial ones:

https://git-wip-us.apache.org/repos/asf?p=lucy.git;a=commitdiff;h=0e49ac6f6ca45860d5598060b89bdac3fbfed2db

https://git-wip-us.apache.org/repos/asf?p=lucy.git;a=commitdiff;h=a5aa40a93d0b2542dc04afd387619b015cf273b5

It would be interesting to know whether they make a difference in Nick D.’s case. If they
solve his problem, we should consider backporting the fix to the 0.3 branch.
