 // (A search keyword is a keyword with a replacement string; a bookmark keyword
 // is a keyword with no replacement string, that is, a shortcut for a URL.)
 //
 // There are two possible providers for search suggestions. If the user has
 // typed a keyword, then the primary provider is the keyword provider and the
 // secondary provider is the default provider. If the user has not typed a
 // keyword, then the primary provider corresponds to the default provider.
 //
 // Search providers may supply relevance values along with their results to be
 // used in place of client-side calculated values.
