Mongodb Query queries

Query.all ("name", "a", "B");//match array with multiple elements
Query.and (Query.eq ("name", "a"), Query.eq ("title", "T"));//satisfy multiple conditions at the same time
Query.eq ("name", "a");//equals
Query.exists ("type", true);//Determine if key value exists
QUERY.GT ("value", 2);//Greater Than >
Query.gte ("Value", 3);//greater than or equal to >=
Query.in ("name", "a", "B");//Includes all values specified, you can specify different types of conditions and values
query.lt ("value", 9);//Less than <
Query.lte ("value", 8);//less than or equal to <=
Query.mod ("Value", 3, 1);//Divide the query value by the first given value and return the result if the remainder equals the second given value
Query.ne ("name", "C");//Not equal to
Query.nor (array);//do not include values in the array
Query.not ("name");//Element conditional statement
Query.notin ("name", "a", 2);//Returns a document that does not match all the conditions in the array
Query.or (Query.eq ("name", "a"), Query.eq ("title", "T"));//satisfies one of the conditions
Query.size ("name", 2);//The length of the given key
Query.type ("_id", bsontype.objectid);//The type of the given key
Query.where (bsonjavascript);//execute JavaScript
Query.matches ("Title", str);//fuzzy query equivalent to SQL in like--STR can contain regular expressions
