lt( )

Creates a search filter for matching documents whose specified field value is less than the specified value.

Description

The lt() function is chained to a WixSearchFilterBuilder to create a WixSearchFilter. You can use the filter to match documents where the value of the specified field is less than the specified value.

lt() only matches values of the same type. For example, a number value stored as a String type does not match the same number stored as a Number type.

If a field contains a number as a String, that value will be compared alphabetically and not numerically. Documents that do not have a value for the specified field are ranked lowest.

The following types of properties can be compared:

Number: Compares numerically.
Date: Compares JavaScript Date objects.
String: Compares lexicographically, so "Text" is less than "text".

Syntax

function lt(field: string, value: string | number | Date): WixSearchFilter
