When searching for words or phrases use the entire word and exact spelling. "Im not hungry" will not work, you need to use "I'm not hungry".

If you are searching for English words that have diacritics, like "pâté", "naïve" or "touché". Just use the English characters, so "pate", "naive" and "touche".

Other than apostrophes all punctuation and diacritics have been removed, so do not include these in queries. Capitalization does not matter.
