All searches are case insensitive, capitalization does not matter. If more than one contact match the search a list of results is returned. If only one contact meets the search criteria you are redirected to that contact.
Entering a string in the normal search box means that a search will be performed where:
If multiple words are used then all words must match the above critera. So, for example if our contacts database contains these entries:
Contact ID | First Names | Last Name | Organization Name --------------+----------------+---------------+--------------------------------- 123 | Jane | Doe | 234 | John | Doe | 345 | Alfred | Hitchcock | 456 | | | United States Treasury
If in a normal search we search for "D Jane". The first Search_Word ("D") matches contacts 123 (via "Doe"), 234 (via "Doe"), and 345 (via "Alfred"). And the second Search_Word ("Jane") matches only contact 123. Thus only one contact meets both requirements and "Jane Doe" (contact 123) is returned.
Advanced searches are very powerful but in return they require very specific input...
