You may want to look at hurry.query.Text. If you index something using a 
full text index (from zope.app.catalog.text import TextIndex) you can do 
such partial matching.

This does presume you do have the intids and catalog all set up in your 
own code. Does hurry.query.Eq work when you feed it a complete text, 
such as "As Built Documentation"?

It may also be that you want to reorganize your objects slightly so that 
you have *two* fields, one 'As Built' and one 'Document' or 'Drawing'. 
It could be that you're trying to put information into one field that 
really should be in multiple fields. If you do that, you can use the 
Field index and query.Eq.

Good luck!
