skip range scan index selection choosing longest matching index

Create default bucket

Insert docs like the following:

{a:100, d:200}

create 4 indexes:

create index idx1 on default(a, d);
create index idx2 on default(a, b, d);
create index idx3 on default(a, b, c, d);
create index idx4 on default(a, b, c, d, e);

run queries:

select * from default where a > 0 and d > 0;
select a, d from default where a > 0 and d > 0;

In both cases idx3 will be selected which results in unnecessary extra work
