query = "(user can be admin)"
  -> check all fields for the given words. If all words are found in a combination of any
  fields, document is a match.

query = @(title,content) (user can be admin)"
  -> check title and content fields for the given words. If all words are found in a
  combination of title and content, document is a match.

> Where I want all the words (user can be admin) should be in title or content.

The query you want:
query = "(@title user can be admin) | (@content user can be admin)"

实测有效！
