The search text should be in all lower-case, each word separated by a single space, and should be stripped of all punctuation. Most contractions should be spelled out as full words. As you may notice in the example above, some simple, very common contractions may be excluded. Numbers greater than 100 should only be in numeric format. Most sound effects should be excluded.
Notable exceptions are sound effects that are important to the joke.
Again, hyphens should be replaced with spaces. Signs should be included if they are essential to the joke. Deliberate misspellings should be recorded both as is and corrected. Again, I haven't been very strict on this rule myself, but this is a good one to follow. When the words are actually spelled out, they should be left spelled out.
