hi,

yes, we are using 1.0.13, with libxapian.so.15.6.4.  So, what are our
options, will upgrading to 1.0.14 fix this, or do we need to wait until
1.0.15?

we are intending to use the merge so we can index smaller, one day databases
and merge them into a larger running database.  do you know if generally
this is faster than just continuing to index the larger database?

thanks for your help,
Paul
