Unable to work without search_field

[remster]

Hi. The in-source comments say:
"You can also give a 'search_field', a VectorField into where the values of the searched
fields are copied and normalized. If you give it, the searches will be made on this
field; if not, they will be made directly in the searched fields."

If i understand the concept correctly, search_field is an aux vector/array column with all searchable values copied in and kept up-to-date with update_search_field.

I cannot keep them up to date this way because someone else is writing to db. My django is readonly.

But the SearchQuerySet does simply this:
full_search_field = "%s.%s" % (
qn(self.model._meta.db_table),
qn(self.manager.search_field)
)
w/o ensuring search_field exists and I am seeing a callstack.

Can u confirm my diagnosis is correct? I may be able to contribute as i need this kind of function.
