1. A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor to perform: detecting a search token mnemonic in a string, wherein the string comprises one or more operators selected from the group consisting of arithmetic operators, logical operators, text operators, formatting operators, and date operators and the search token mnemonic is associated to a search token comprising two or more search definitions and a balance value, each search definition specifies a search rule for one or more dissimilar search paths and that comprises a search path, a capture label, a system output status, a search event, a history range that specifies a number of historical search results that trail search results, a historical function that is applied to the search results, a result type, and a capture tag; searching the search paths using the search rule, wherein the balance value is in balance when the two or more search definitions each retrieve search results in the search event and the search token is resolved to a Boolean TRUE, the balance value is out of balance when the search token is resolved to a Boolean FALSE, and the search token is undefined when any one of the two or more search definitions does not retrieve search results; performing an operation specified by the one or more operators on the search results for the search token mnemonic; and replacing the search token mnemonic with a search result in the string in response to the balance value being in balance.
