sortExpression property
An expression that computes a score for each suggestion to control how they
are sorted. The scores are rounded to the nearest integer, with a floor of 0
and a ceiling of 2^31-1. A document's relevance score is not computed for
suggestions, so sort expressions cannot reference the _score
value. To sort suggestions using a numeric field or existing expression,
simply specify the name of the field or expression. If no expression is
configured for the suggester, the suggestions are sorted with the closest
matches listed first.
Implementation
final String? sortExpression;
