Question

suppose you want to find pages that contain the word german but not the word shepherd. which search would achieve this? choose the answer
german shepherd
german - shepherd
german or shepherd
german + shepherd

Explanation:

When using search engines, the "AND" operator (implied by just writing words together like "German Shepherd") finds pages with both terms. The "OR" operator would find pages with either term. We want pages with "German" but not "Shepherd", so we use the minus sign (equivalent to excluding a term in some search logics). "German - Shepherd" would exclude pages with "Shepherd" while including those with "German".

Answer:

German - Shepherd
