Twitter has about 500 million tweets every day. However, not all of them are available in the search feature within Twitter. Here are a couple advanced search tips to help you find what you’re looking for:
For exact phrases use quotes (“”) around your search term. This is especially useful when your search includes slang, abbreviations, names, or acronyms. For example, in the search box type “shoplifter hits.” This will help eliminate false positives and only return results with the exact phrase “shoplifter hits.”
For tweets from a specific person or organization, type in their handle preceded by the @ sign (for example, “@cnn”). This will only return results tweeted by “@cnn.” This can be helpful in investigations when you know the suspect’s twitter handle (user name).
