> “||” will perform the function of STRING concat, and it is also the symbol of the "OR" operation.
> When I want use "||" as "OR" operation, I find that it perform the function of STRING concat，
>   spark-sql> explain extended select * from aa where id==1 || id==2;
>    == Parsed Logical Plan ==
>     'Project [*]
>      +- 'Filter (('id = concat(1, 'id)) = 2)
>       +- 'UnresolvedRelation `aa`
>    spark-sql> select "abc" || "DFF" ;
>    And the result is "abcDFF".
> In predicates.scala, "||" is the symbol of "Or" operation. Could we remove it?
