Proximity ranking

Strictly speaking, all keyword search results are equally relevant: either they satisfy the Boolean expression, or they do not. However, the results that are likely to be more relevant to the user will have the query words closest together in a sentence and in the same order as specified in the query.

Keyword search results are sorted using proximity ranking. This means that the results at the top of the list contain query words in the same order as specified in the query and closest to one another.
