oracle.ultrasearch.query
Class Equals

java.lang.Object
oracle.ultrasearch.query.Equals

All Implemented Interfaces:

Query

public class Equals

extends java.lang.Object

implements Query

Find documents with an attribute that equals a value.

Equality is interpreted differently for each attribute type. For DateAttribute, only the year, month, day parts of Date values are used in comparison. For NumberAttribute, only 32 bits of precision are used in comparison. For StringAttribute, equality is based on hash value, so there is a small probability of error when results are returned.

Since:

9.0.2
