   *   search expression, or NULL if no keywords should be set for this input.
   *   An array will contain a '#conjunction' key specifying the conjunction
   *   type, and search strings or nested expression arrays at numeric keys.
   *   Additionally, a '#negation' key might be present, which means – unless it
   *   maps to a FALSE value – that the search keys contained in that array
   *   should be negated (that is, not be present in returned results). The
   *   negation works on the whole array, not on each contained term
   *   individually – that is, with the "AND" conjunction and negation, only
   *   results that contain all the terms in the array should be excluded; with
   *   the "OR" conjunction and negation, all results containing one or more of
   *   the terms in the array should be excluded.
