Michelle wants to search for a scuba regulator. She plans to use a keyword search engine. She does not want to see any results from the manufacturer named Scubapro. Which of the following search…

Question

Options

• ARegulators !Scubapro
• BRegulators Scubapro
• CRegulators <Scubapro
• DRegulators >Scubapro

• A
  96% (24)
• C
  4% (1)

Explanation

Option A is correct because the ! operator (sometimes called the "NOT" or exclusion operator) tells the search engine to exclude results containing the specified term - in this case, anything from or about Scubapro. The query Regulators !Scubapro returns regulator results while filtering out Scubapro content.

Why the distractors are wrong:

• B (Regulators Scubapro) - no exclusion operator is used, so the search engine will include Scubapro results, the opposite of what Michelle wants.
• C (Regulators <Scubapro) - the < symbol is not a recognized search exclusion operator; it has no standard meaning in keyword search syntax.
• D (Regulators >Scubapro) - similarly, > is not a search exclusion operator and would not filter out Scubapro results.

Memory tip: Think of ! as "NOT" - in many programming and logic contexts, ! means negation or "not this." So !Scubapro = "NOT Scubapro." If you remember != means "not equal to" in coding, the same logic applies here.
