    <p>This is a problem that is not necessarily unique to FileMaker. You are searching for a name that is imprecise because it is a match for multiple names. Rather instead you might want to search for a unique key <strong>whose subject name</strong> is 'Mathematics' as displayed in your drop down. It is the use of that unique key that allows you to perform a precise search, even when the name of one subject is a partial or complete match for another.</p> <p>This solution requires you to add a unique serial number which is, in your case, to alter the Subjects table and add a field called 'idnumber' or similar. The field type should be <em>Number</em>, and the options should include <em>Auto-Enter-Serial number-Generate</em> and <em>On creation-increment by 1</em>. The trick here lies in making sure no two subjects have the same 'idnumber' even when you aren't paying attention, so set the <em>next value</em> to something greater than the number of subjects that already exist. Then from another layout assign each existing subject a unique idnumber, noting that if there are a great many subjects you could script that step. </p> <p>I should mention that many recommend a best practice of never changing a production layout, but rather to duplicate the layout and make the required changes to the duplicate. This minimizes the effects of testing your changes etc.</p> <p>Finally, change your layout in inspector such that the drop down list shows <em>Use values from field: 'idnumber'</em>. Select <em>Also display values from second field: 'Subject'</em> and <em>Show values only from second field</em>. Now your drop down is the same clean selection as before. The field will not look correct yet because it will show a number. To make it look correct you can insert another field, selecting 'Subject'. Place that field over top of the 'idnumber' and send 'idnumber' to the back. Fill the 'Subject' field with the correct background solid color instead of none, and enjoy your new precision search capability! The entire process is handled server side so it should not matter that client access is IWP.</p>
