RethinkDB Compound Index Weirdness Using Between

问题

I've noticed something strange with compound indexes in the between function in RethinkDB. It seems to retrieve results that don't match the query. It's all detailed below.

r.dbCreate('test')

r.db('test').tableCreate('numbers')

r.db('test').table('numbers').insert([
    { first: 1, second: 1 },
    { first: 1, second: 2 },    
    { first: 1, second: 3 },    
    { first: 1, second: 4 },    
    { first: 1, second: 5 },    
    { first: 2, second: 1 },    
    { first: 2, second: 2 },    
    { first: 2, second: 3 },    
    { first: 2, second: 4 },    
    { first: 2, second: 5 },    
    { first: 3, second: 1 },    
    { first: 3, second: 2 },    
    { first: 3, second: 3 },    
    { first: 3, second: 4 },    
    { first: 3, second: 5 },
    { first: 4, second: 1 },    
    { first: 4, second: 2 },    
    { first: 4, second: 3 },    
    { first: 4, second: 4 },    
    { first: 4, second: 5 },    
    { first: 5, second: 1 },    
    { first: 5, second: 2 },    
    { first: 5, second: 3 },    
    { first: 5, second: 4 },    
    { first: 5, second: 5 }
  ])

r.db('test').table('numbers').indexCreate(
    "both", [r.row("first"), r.row("second")])

r.db('test').table('numbers').orderBy({index :'both'}).between(
  [2, 3], [3, 5], {index: 'both', rightBound: 'closed'}).without('id')

// output

{ "first": 3 , 
"second": 3 
} // ok

{ "first": 3 , 
"second": 4 
} // ok

{ "first": 2 , 
"second": 5 
} // ok

{ "first": 3 , 
"second": 1 
} // not ok

{ "first": 3 , 
"second": 5 
} // ok

{ "first": 3 , 
"second": 2 
} // not ok

{ "first": 2 , 
"second": 3 
} // ok

{ "first": 2 , 
"second": 4 
} // ok

The array in the query doesn't appear to act like an AND or an OR. Am I missing something or is this a bug?

回答1:

Ok so thanks to some help from originalexe over on the Slack channel I've figured this out. It's behaving as normal and essentially the array is treated as a single value and the query returns all values that are between the two in an ordered list.
