Incorrect method for inspecting ambiguous results

[ehenneken]

This looks like a bug, but an additional set of eyes is needed to confirm that it actually is.

When no candidate solutions are found with a score above a the minimal score, and there actually are candidate solutions, the doubtful solutions are inspected.

    if len(filtered)==0:
        if candidates:
            current_app.logger.debug("No score above minimal score, inspecting doubtful solutions.")
            return inspect_doubtful_solutions(candidates, query_string, hypothesis)
        raise NoSolution("Not even a doubtful solution")

However, the call inspect_doubtful_solutions(candidates, query_string, hypothesis) seems incorrect and probably should have been

inspect_ambiguous_solutions(candidates, query_string, hypothesis)

This method actually returns, while the current call only raises exceptions.
