Not much progress with the tweaking: shifted instance-variable access in the bottleneck function to use a local variable instead but it's made no difference. I suspect that the loop involved doesn't run more than once or twice per invocation, so the instance-var access overhead isn't a big deal.

Going to revert to lucene 1.2 API for the July release, but will see if the index-merge tuning can remain in place. Aim to migrate to 1.4 next month after further tuning.

Worked with Steve on his final day to integrate the did-you-mean functionality into the xrefer client API. It's in and working via the testapi page. Need to rename the db table and put it up to w1 ready for the july release.

This is the third time of trying to publish this post in three days. I think blogger's having problems.
