+npm-help-search(3) -- Search the help pages
+===========================================
+
+## SYNOPSIS
+
+    npm.commands.helpSearch(args, [silent,] callback)
+
+## DESCRIPTION
+
+This command is rarely useful, but it exists in the rare case that it is.
+
+This command takes an array of search terms and returns the help pages that
+match in order of best match.
+
+If there is only one match, then npm displays that help section. If there
+are multiple results, the results are printed to the screen formatted and the
+array of results is returned. Each result is an object with these properties:
+
+* hits:
+  A map of args to number of hits on that arg. For example, {"npm": 3}
+* found:
+  Total number of unique args that matched.
+* totalHits:
+  Total number of hits.
+* lines:
+  An array of all matching lines (and some adjacent lines).
+* file:
+  Name of the file that matched
+
+The silent parameter is not necessary not used, but it may in the future.
