Then u have to use the table for creating the query and use "Like[Forms]![Fsearch]" in criteria
through Expression builder
If ur an Front end user then following commands.,ill be
Enter to specified front end (i.e.Formview -FSearch)- Then go to design view ,Properties , Data tab ,give data entry "yes".
