--------

Here is the line which calls the search:

sr = self.searchResults({'Type' : type, 'sort_on':'lowercase_title_'})

fyi. type = 'TypeTest'

The indexes are as follows:
Status = Text Index
Type = Field Index
Identifier = Field Index
lowercase_title_ = Field Index
parent_identifiers_ = Keyword Index

The meta types are like this:
Title
id
identifier

There are only 13 records in the catalog.
And there are some results to be returned.

Cheers
