Class PrefixNode

java.lang.Object

com.exalead.search.query.node.Node

com.exalead.search.query.node.UnaryNode

com.exalead.search.query.node.PrefixNode

public class PrefixNode
extends UnaryNode

The content of this is contained in a "prefix". A field can be handled by custom code or by a standard QueryPrefixHandler. A prefix contains a numerical matching operator which can be used to perform a different match. For example: size:42 size==42 size<42
