Search filtering in alert_on_new_query_results

[scottmconway]

SGW doesn't do a great job of allowing the user to make complex query strings. For example, I get the same results if I search with the following queries:

• foo bar
• "foo bar"

Advanced query features:

• sub-string search - parse single/double quotes and search for the substring in the item title
• description search(?) - note that we can only remove results from the search, so this probably won't be useful.

Since advanced queries will still utilize the search text field, we can simply modify the results before they're delivered to the user, further filtering based on the user's advanced requirements.

Closing for now - I might open another issue in the future if I wish to pursue additional advanced query features.
