show xxx|section "string" include "string2"

The command xxx is executed and the output is filtered to only show lines included within the section(s) identified by lines containing the "string" match and ending with the first line containing the default end-of-section identifier (i.e. "exit") and that include the "string2" match. This type of filter command could also include "exclude" or user-defined end-of-section identifier parameters as well.
