The monitoring search supports the st: search operator for filtering by a specific state, i.e. st: warn. However, the only way to filter on multiple states was to call the operator multiple times like st: warn st: crit. With this change, it is now possible to invoke the pipe operator to get this same behavior: st: warn|crit. We also handle the case that this or statement is wrapped in parentheses, so this is also a valid filter: st: (warn|crit).
