Thanks.  I took this file and adapted the test cases I wrote yesterday.  Here
are the results I got:

[1] main heading contains "wil"

GRS-1 = 27 hits
DOM   = 27 hits

[2] all headings contains "wil"

GRS-1 = 27 hits
DOM   = 27 hits

[3] keyword contains "wil"

GRS-1 = 27 hits
DOM   = 29 hits

The following indicates that the DOM filter is not necessarily wrong:

$ perl -ne 'BEGIN { $/ = "\035"; } END { print "$ct\n" } { $ct++ if /wil/i; }'
< unimarc_auth_3.mrc 
29

IOW, there really are 29 records that contain the substring "wil".

I'll investigate further to see why the GRS-1 any index is behaving slightly
differently.
