Flush on search custom command not working

New Member

I try to use flush on custom command and not working.

I used generatetext.py from searchcommands_app and put self.flush() and the search done with errors.

    def generate(self):
        text = self.text
        self.logger.debug("Generating %d events with text %s" % (self.count, self.text))
        for i in range(1, self.count + 1):
            yield {'_serial': i, '_time': time.time(), '_raw': six.text_type(i) + '. ' + text}
            self.flush()

Error:
