Use ora:contains with a full sentence (Oracle 11g)

Question

Hello to all.
I execute this query:
SELECT d.* from Document d WHERE ( ( (( d.XML.existsNode('//field[ora:contains(@value,"*forni di sopra*","ai_my_policy") and  @fieldId="FE1195216030414741158"]','xmlns:ora="http://xmlns.oracle.com/xdb"') = 1) AND d.IDTEMPLATE=265) ) )
And the system give me this result:
<field name="Luogo" searchable="true" listable="false" fieldId="FE1195216030414741158" required="" taggable="false" iterable="false" isIterate="false" type="vocabulary" specification="" vocabulary="280" vocabularyOrig="FE1195216030414741158" value="*Forni di Sotto*"/>
Why?
I have no result is I search: ora:contains(@value,"*sopra*","ai_my_policy")
My policy is:
BEGIN
CTX_DDL.create_preference(PREFERENCE_NAME => 'ai_my_lexer',
OBJECT_NAME => 'BASIC_LEXER');
CTX_DDL.set_attribute(PREFERENCE_NAME => 'ai_my_lexer',
ATTRIBUTE_NAME => 'BASE_LETTER',
ATTRIBUTE_VALUE => 'YES');
CTX_DDL.create_policy(POLICY_NAME => 'ai_my_policy',
LEXER => 'ai_my_lexer');
END;
Thank you,
Cristian
