Search indexing is prohibitively slow for large CCX courses, even taking hours in the case of some particularly large ones with thousands of blocks. Temporarily disabling this functionality until it can be made more performant (PSRE-288), so that we're not blocking the workers from doing more latency-sensitive work. There is a separate effort to put search indexing in its own set of workers.
