Improving Search

I was really disappointed when I tried to find a phrase, and found that your search only operates on single words.

I checked your search syntax help, and you have countless options and filters, but no way to search for a string which includes one or more spaces? 

If I want to dig up an old post in the Fan Theories room to congratulate a correct theory (once it happens in my video series, so it ceases to be a spoiler), I need to be able to search for something like "Black's father". Black is a main character - that name could come up hundreds of times. And there are a ton of theories about another protagonist's father. Searching either word individually is near-useless, whereas searching the two together would near-instantly find what I'm looking for.

As someone who uses search on other sites all the times, any decent search has the ability to enclose a string in special characters (usually quotation marks) to search for that term "as-is", including spaces, punctuation, etc. I can't even understand why you'd make a search without that feature.
