      As of 3.1.7, a partialFilterExpression of {field: {$type: 'number'}} only supports the following queries:

      {field: {$type: 'number'}}
{field: {$type: 'number'}, anotherField: ...}

      An improvement could be made to answer the following class of queries:

      // Comparison operations involving numbers
{field: 10}
{field: {$lt: 20}}
{field: {$in: [30, 40, 50]}}
// $type queries for double, int, and long.
{field: {$type: 'int'}}
{field: {$type: 1}}
