You would use a query for that. Create a new query and open it in SQL view (how to do this depends on what version of Access you are using). Now enter the following (correcting the names of course)
- SELECT *
-
FROM YourTableNameHere
-
WHERE Field1 = 'Jane Doe'
If Field1's actual field name is "Name" (which would be bad because that is a reserved word), then you would need to surround it in square brackets ([]). Now granted, this is very manual in that if you want to look for John Doe, you have to go back into Design or SQL view to change the name, but without more details about how your database is setup, we can't go much farther in helping you. Also, if someone entered two spaces between Jane and Doe, then that record wouldn't be found. Also misspelling. Capitalization would depend on the settings of the database.
If this is a database that you are designing, then you should look at
Database Normalization and Table Structures for information about how best to structure your tables in a way that makes everything much easier.
