search for subscribers breaks on certian phrases

[Mr. Jolly]

The catalog throws an exception if certian phrases are used in the search for subscribers such as 'a' and 'it' plus other common words that are deemed to common to catalog. Obviously search for a would be common looking for all those people starting with a. 'it' maybe searching for italian sites. A quick fix would be to catch the errror and then append a '*' to the query eg.

line 262 in collective.dancing.browser.channel.py to something like:

        try:
            subscriptions = self.context.subscriptions.query(**query)
        except:
            query['fulltext'] = query['fulltext'] + '*'
            subscriptions = self.context.subscriptions.query(**query)

This will however pull in anything with an 'a' in it, so further coding would be needed maybe something as simple as organising the search results in alphabetical order something like...

        emails = [i.composer_data['email'] for i in subscriptions]
        emails.sort()

        for email in emails:
            for i in subscriptions:
                if i.composer_data['email'] == email:
                    subscription = i
                    if subscription.metadata['format'] == self.format:
                        items.append((str(subscription.secret), subscription))
        return items

its a bit of a fudge but any other solutions?
