Is there an issue with the LIKE statement in a query in Access when it's
applied to a mailmerge query from Word?

I have a problem at a client location, and I'm not able to reproduce the
issue on my own systems. XPPro, Word and Access 2003 is the environment, and
within Access I have a query that includes a criteria

LIKE "*G05*"

against a field in the database.

In Access, the query works correctly and returns 25 records from a database
of almost 2000 records.

On the same system, when I go into Word and specify the database/query in
preparation for a mailmerge, there are no records selected or displayed.

Using the same query back in Access, if I remove that criteria, the query
now returns the full complement of records in the table, and then reloading
the query in Word also now sees the query working correctly.

Similarly, feeding a simple criteria against a different field (= "US")
works under both applications, so it seems as if it comes back to some sort
of issue, perhaps related to the LIKE statement, and how it translates
through to the Word document and its query aghainst the database.

Has anybody seen something like this before?

Are there any workarounds that can be used?
