There is indeed no dedicated public API to manually call the underlying protected org.nuxeo.ecm.core.storage.sql.SessionImpl#updateFulltext() in the current version. The only way to force and update of the fulltext columns is to modifiy a text field and a the attached file of the document.
Extending the repository API to provide methods to trigger batch fulltext updates (either from the text fields, either from the binary attachements using the converters, or from both) would be interesting but such a development is not scheduled AFAIK. --- Mailing list: [email protected] Forum: http://forum.nuxeo.org/f/1/
