[Zope-CVS] CVS: Products/ZCTextIndex/tests - testZCTextIndex.py:1.21

[Tim Peters]

Update of /cvs-repository/Products/ZCTextIndex/tests
In directory cvs.zope.org:/tmp/cvs-serv13140/tests

Modified Files:
	testZCTextIndex.py 
Log Message:
Added a number of tests to trigger search-can-return-None bugs.  The three
tests that currently fail are currently commented out.

Key question:  If someone does a search on a stopword, and nothing else is
in the query, what do we want to do?  Return all docs in a random order?
Return no docs?  Raise an exception?

Second question:  What if someone does a query on

    rare_word AND NOT stop_word

?
