While the simple search form only searches on last names, you can narrow your searches using these signs:
+ A leading plus sign indicates that this word must be present in every record returned.
- A leading minus sign indicates that this word must not be present in any record returned.
* An asterisk is put in place of a letter or series of letters to search by the first part of a word. It can only replace letter(s) at the end of a word. The * can be used with the + and - signs
" " Double quotes at the beginning and end of a phrase, matches only records that contain the complete phrase, as it was typed.
