When searching in CentraSite you can search for a name (the name, as well as the description of the service is searched here) or a service ID.
You can use % or * as a placeholder for one or more characters (not in the ID field). For example, the entry of ABC%DEF or ABC*DEF returns all strings that start with ABC, end with DEF and have any number of any type of characters in between. The % or * placeholder is automatically assumed at the end of a string. You can restrict the search to the service status and the person responsible.
