Determination of schema compatibility between neighboring operators within a search query statement

A system comprising:

• a processor;
• and
• a non-transitory computer-readable medium having stored thereon a query validation component that, when executed by the processor, performs operations including:
• obtaining a query;
• identifying a sequence of operators associated with the query, the sequence of operators includes at least two neighboring operators including a first operator and a second operator representing a machine learning model;
• determining a schema associated with the first operator and a schema associated with the second operator, wherein determining the schema of the second operator includes retrieving metadata of the machine learning model which indicates an input and an output of the machine learning model;
• determining compatibility between the schema of the first operator and the schema of the second operator;
• and
• generating a query error message in response to incompatibility between the schema of the first operator and the schema of the second operator, wherein the generating of the query error message comprises returning the query error message to a web-based application.

A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, cause performance of operations comprising:

• obtaining a query;
• identifying a sequence of operators associated with the query, the sequence of operators includes at least two neighboring operators including a first operator and a second operator representing a machine learning model;
• determining a schema associated with the first operator and a schema associated with the second operator, wherein determining the schema of the second operator includes retrieving metadata of the machine learning model which indicates an input and an output of the machine learning model;
• determining compatibility between the schema of the first operator and the schema of the second operator;
• and
• generating a query error message in response to incompatibility between the schema of the first operator and the schema of the second operator, wherein the generating of the query error message comprises returning the query error message to a web-based application.
