2. How to get the information:

        STRING          Broad search all over the types
        !STRING                 Key search all over the types

To restrict the search to a certain type of information:

        TYPE STRING     TYPE is one of DOM, NET, etc. (see above)

To obtain detail or related information:

        *STRING                 Expand the output even when multiple matches
        %STRING                 Expand the contact fileds or known sub-domains
        ^STRING                 Display what refers to the information

When you don't know exactly:

        STRING...       Partial search starting with STRING
        ...STRING       Partial search ending with STRING

if STRING contains an '@', search only E-Mail fields:

        name@           Find everyone with the name.
        @domain                 Find everyone in the domain.
        name@domain     Find everyone with the name in the domain.
