Seems like a good feature. I don't know how I would use Postgres text search without it.
It's still throwing an error on line 1194:
File "/Users/pbreit/web2py/gluon/dal.py", line 1194, in _select
if query and not query.ignore_common_filters:
AttributeError: 'str' object has no attribute 'ignore_common_filters'
