Title: Support negative search with hyphen-minus (-) sign.

This allows searching for errors excluding the search text.

An example use case: all our JavaScript errors are logged at a certain URL, `/LogJSError`. With this change it's possible to search for `-LogJSError` and retrieve the server-side errors only.
