There is no easy way to do this because it does not make sense in a
normalized Access database. Each field should contain a specific type of
data. A user should not be able to enter "a word" anywhere in the table.
The date field, record number, customer name, etc. fields would not contain
a key word, for example.
What is your data structure? Why would you search for a specific word in
any field, instead of the field where the word should be entered?
My fear is that you do not have a normalized database. Post more about your
data structure.
