The concept of "Google hacking" dates back to August 2002, when Chris Sullo included the "nikto_google.plugin" in the 1.20 release of the Nikto vulnerability scanner. [4] In December 2002 Johnny Long began to collect Google search queries that uncovered vulnerable systems and/or sensitive information disclosures – labeling them googleDorks.
2. For the similar-looking operator named parallel, see ∥. ⌊ ⌋ Floor function: if x is a real number, ⌊ ⌋ is the greatest integer that is not greater than x. ⌈ ⌉ Ceiling function: if x is a real number, ⌈ ⌉ is the lowest integer that is not lesser than x. ⌊ ⌉
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [2] [3]

The operator precedence is a number (from high to low or vice versa) that defines which operator takes an operand that is surrounded by two operators of different precedence (or priority). Multiplication normally has higher precedence than addition, [ 1 ] for example, so 3+4×5 = 3+(4×5) ≠ (3+4)×5.
In 2019 Google published a paper presenting "Zanzibar: Google’s Consistent, Global Authorization System". [2] The paper defines a system composed of a namespace configuration and relationship data expressed as triples. Since the release of that paper, several companies have built commercial and open source offerings of ReBAC systems.
The following examples use a syntax supported by Google. [NB 1] Doublequotes are used to combine whitespace-separated words into a single search term. [NB 2] Whitespace is used to specify logical AND, as it is the default operator for joining search terms: "Search term 1" "Search term 2" The OR keyword is used for logical OR:
In mathematics, an operator or transform is a function from one space of functions to another. Operators occur commonly in engineering, physics and mathematics. Many are integral operators and differential operators. In the following L is an operator :
