Searching (CONTAINS) on OrdDoc columns...

Question

I have a table containing an ordDoc column, among others:
CREATE TABLE MY_DOCS (number ID, ordsys.orddoc DOC_BODY);
The OrdDocs are a mix of PDF and Word, majority being Word.
I have successfully managed to create a Context index on the document column:
CREATE INDEX MY_INDEX ON MY_DOCS(DOC_BODY.source.localdata)
INDEXTYPE IS CTXSYS.CONTEXT;
There are no errors in ctxsys.ctx_index_errors, and I have loaded up some documents and done a Synch:
ctx_ddl.sync_index('MY_INDEX', '2M');
But when I try a CONTAINS query -
SELECT score (1), id FROM MY_DOCS WHERE CONTAINS(doc_body, 'forensic', 1) > 0;
I get the following errors:
ORA-29900: operator binding does not exist
ORA-06553: PLS-306: wrong number or types of arguments in call to 'CONTAINS'
I have also tried
SELECT score (1), id FROM MY_DOCS WHERE CONTAINS(DOC_BODY.SOURCE.LOCALDATA, 'forensic', 1) > 0;
with the result
ORA-00904: "DOC_BODY"."SOURCE"."LOCALDATA": invalid identifier
SO the question then is... how DO I do a CONTAINS query against the ORDDOC Column?
thanks

Thanks Lawrence,
I found it also works with a column alias, and you need to add the .source.localdata
ie:
SELECT score (1), id FROM MY_DOCS d WHERE CONTAINS(d.doc_body.source.localdata, 'forensic', 1) > 0;
