# QueryError

> A QueryError holds the definition of a query parsing error.

## Definition

## Remarks

QueryErrors are obtained when parsing a query through the function QueryEngine.Parse. See [QueryEngine](/engine/6000.7/script-reference/unityeditor/search/queryengine1.md) for an example where we recover parsing errors when a query is invalid.
