Thanks *very much* for replying. (You're right, I missed the "zero or more,"
having focused only on the examples in the doc. Oops).
New discovery. kin*ase returns 0 hits. Below I show the debug output and the
pertinent parts of the schema. Maybe you can spot my problem?

Subject: [External] Re: wildcards match end-of-word?
“kinase*” does match “kinase”. On the page you linked to, it defines “*” as
matching "Multiple characters (matches zero or more sequential characters)”.
If it is not matching, you may be using a stemmer on that field or doing some
other processing that changes the tokens.
