• Using parameters of <, <=, =, =>, > against a constant, such as a date or file size.
• Using Boolean operators, AND, OR, AND NOT.
• Using wild cards, such as "*", "?" and regular expressions for "fuzzy" queries (example: "dev*" will bring up all words that start with "dev" including "development" and "developers")
