Data Store Query Limits

Query objects specify conditions for selecting documents. For query object structure and syntax, see Data Store Query Object.

The following table lists the query input limits. Byte limits are measured after UTF-8 encoding. A character can use more than one byte.

Complete field path, including dots and nested property names	256 bytes
String comparison value	4,000 bytes
Numeric comparison value	`0`, or an absolute value of at least `1e-130` and less than `1e126`
Operators in a query expression, including implicit comparisons and logical connectors	300
