Using BLOB with ctx_doc.filter

I have a question about ctx_doc.filter. If I have this sentence -- ctx_doc.filter('myindex','1', mklob, TRUE); -- and mklob is the CLOB datatype, this works fine, but if I have mklob as a BLOB, it doesn't. Do you know if Oracle have another function to work with BLOB?

Hi Greg. I have a question about ctx_doc.filter. If I have this sentence -- ctx_doc.filter('myindex','1', mklob, TRUE); -- and mklob is the CLOB datatype, this works fine, but if I have mklob as a BLOB, it doesn't. Do you know if Oracle have another function to work with BLOB?
Use: ctx_doc.ifilter(). This procedure is used with BLOBs.

The procedure looks like this:

  PROCEDURE ifilter(
    data   IN            blob,
    text   IN OUT nocopy clob
  );
