rankingExpression

string

Required. Controls over how job documents get ranked on top of existing relevance score (determined by API algorithm). A combination of the ranking expression and relevance score is used to determine job's final ranking position.

The syntax for this expression is a subset of Google SQL syntax.

Supported operators are: +, -, *, /, where the left and right side of the operator is either a numeric Job.custom_attributes key, integer/double value or an expression that can be evaluated to a number.

Parenthesis are supported to adjust calculation precedence. The expression must be < 200 characters in length.

The expression is considered invalid for a job if the expression references custom attributes that are not populated on the job or if the expression results in a divide by zero. If an expression is invalid for a job, that job is demoted to the end of the results.
