問題文

A support engineer types the following into the search bar of the Search and Reporting application: failed login. Which events does this search return?

選択肢

1. Events that contain either term, because terms are combined with an implied OR unless the search explicitly requests both of them with AND.
2. No events, since a search has to begin with an index specification before any terms, and a bare pair of words is rejected before it reaches the index.
3. Events that contain both terms, because the two words are combined with an implied AND.
4. Events that contain the exact phrase in that order and with a single space between the two words.
