Question

Which technique improves search accuracy in search engines?

• A. Long paragraphs
• B. Boolean Operators (AND, OR, NOT)
• C. Uppercase only
• D. Avoid Keywords

Hint:

AND = Include both terms
OR = Include either term
NOT = Exclude unwanted term

Answer 1

The Correct Option is B

Concept: Search engines process billions of web pages. To obtain relevant results efficiently, users can employ special search techniques. One of the most effective methods is the use of Boolean Operators.

Step 1: Understand Boolean Operators. Boolean operators are logical operators used to refine search queries. The most common operators are:

• AND

• OR

• NOT
These operators help search engines understand the relationship between keywords.

Step 2: Understand their functions.

AND: Returns results containing all specified keywords. Example:

OR: Returns results containing either of the specified keywords. Example:

NOT: Excludes unwanted terms. Example:

Step 3: Evaluate the alternatives. Long paragraphs often reduce search precision. Using uppercase letters does not significantly improve search accuracy. Avoiding keywords makes searching less effective. Boolean operators directly improve the relevance of search results.

Step 4: Conclusion. Therefore, Boolean Operators are an effective technique for improving search accuracy. Hence, option (B) is correct.
