Searching key-value pairs in alert search yields incorrect results

Issue Summary

Searching key-value pairs in the alert search is returning incorrect results for the status filter on the query.

Steps to Reproduce

1. Search key-value pairs in the alert search
   1. example: status: open AND (incident-alert-type: Owner OR incident-alert-type: responder)

Expected Results

This isn't supported search syntax as far as I'm aware, so I'd expect an error or no results.

Actual Results

Closed alerts are returned with the results.

Workaround

Use the 'detailsPair' search option.

Syntax: detailsPair("key":"value")
