I am confused on the instruction about search function. Here is description in instruction:
UI: It must allow the user to search the data for all records, or for records where the name and/or location fields exactly match values specified by the user.
DB: Returns an array of record numbers that match the specified criteria. Field n in the database file is described by criteria[n]. A null value in criteria[n] matches any field value. A non-null value in criteria[n] matches any field value that begins with criteria[n]. (For example, "Fred" matches "Fred" or "Freddy".)
Does this mean I need to filter the search result data? For example, user enter "Fred: on UI, find() method will reture any record begin with "Fred" (includes "Freddy"). But we need to filter those record which are not exactly "Fred", like "Freddy". And only show the record "Fred" to user.
