Filter Operators

Operator	Description	Example
$eq	Equal to	{"field": {"$eq": "value"}}
$ne	Not equal	{"field": {"$ne": "value"}}
$lt	Less than	{"field": {"$lt": 100}}
$lte	Less than or equal	{"field": {"$lte": 100}}
$gt	Greater than	{"field": {"$gt": 0}}
$gte	Greater than or equal	{"field": {"$gte": 50}}
$in	In array	{"field": {"$in": ["a","b"]}}
$contains	Contains string	{"field": {"$contains": "VIP"}}

$and	Logical AND	{"$and": [cond1, cond2]}
$or	Logical OR	{"$or": [cond1, cond2]}

Best Practices

1. Use paging for large collections (max 1000 items per query)
2. Filter on indexed fields for performance
3. Use aggregation instead of fetching all items for statistics
4. Bulk operations for inserting/updating multiple items (max 1000 per batch)
5. Rate limit: 200ms between queries
6. Schema awareness: Always check collection schema before querying
7. System fields: _id, _createdDate, _updatedDate, _owner are always present
