 - Slow ranking. It is need position information about lexems to ranking. `GIN`
 index doesn't store positions of lexems. So after index scan we need additional
 heap scan toretreive lexems positions.

 - Slow phrase search with `GIN` index. This problem relates with previous
 problem. It is need position information to perform phrase search.
 - Slow ordering by timestamp. `GIN` index can't store some related information

 This operator class stores `anyarrray` elements with length of the array.
 This operator class stores `anyarray` elements with length of the array.
 Supports operators `&&`, `@>`, `<@`, `=`, `%` operators. Supports ordering by `<=>` operator.
 For example we have the table:
