Search npm help documentation
npm help-search <text>This command will search the npm markdown documentation files for the terms provided, and then list the results, sorted by relevance.
If only one result is found, then it will show that help topic.
If the argument to npm help is not a known help topic, then it will
call help-search. It is rarely if ever necessary to call this
command directly.
If true, the "long" flag will cause help-search to output context around where the terms were found in the documentation.
If false, then help-search will just list out the help topics found.
