oracle.ultrasearch.query
Class CtxContains

java.lang.Object
oracle.ultrasearch.query.CtxContains

All Implemented Interfaces:

Query

public class CtxContains

extends java.lang.Object

implements Query

Construct a Query object based on any Oracle Text query string. Oracle Text offers many linguistic features, such as thesaurus (SYN), theme (ABOUT), soundex (!), stemming ($), in its query language. Any valid Oracle Text query can be used as an Ultra Search query by constructing a CtxContains object.

Because CtxContains implements Query interface, it can be combined with any Ultra Search query objects using And/Or, and executed using the Instance.getResult method.

For example, to use stemming on the word "cat":

Query qry = new CtxContains ("$cat");

Or, to use synonym for "dog" in document title searching:

StringAttribute title = instanceMetaData.getStringAttribute("TITLE");
Query qry = new CtxContains ("SYN(dog)", title);

9.0.4
