Yes, the search functionality in Sphinx leaves a lot to be desired, even if you are already writing your own Sphinx plugin it is fairly difficult to add stuff to the search indices in a meaningful way. It's also slow. Overall Sphinx suffers a lot from hardcoding the reST data model and directly working with that.
