摘要：
The invention provides in some aspects digital data processing systems and methods that match search objectives across user accounts. In one such aspect, such a system includes one or more digital data processors that limit access to data associated each of one or more users as a function of credentials, where that data includes information about the associated user, other persons and/or entities (such as, for example, businesses). Search functionality provided in such a system matches search objectives against data associated with multiple said users having different respective credentials to identify data meeting those objectives. And, that search functionality responds to identification of data meeting such an objective by notifying one or more users associated with that data.
