Professor George M. Bergman hints regarding searches:

1. If you preface a string with a carat (e.g. ^abc) you will find only those strings that begin with the given string.
2. Similarly, if you add a dollar sign as a suffix (e.g., abc\$) you will find only those strings that end with the given string.
3. Applying both of the above (e.g., ^abc\$) will result in finding only those names that match the string exactly.
