 UI, as it relies on the API. If your only goal is to restrict search, use `SEARCH_ENABLED` instead.

 * `SEARCH_ENABLED`: `false` disables searching in the query API and any indexing or post-processing
 in the collector to support search. This does not disable the entire UI, as trace by ID and
 dependency queries still operate. Disable this when you use another service (such as logs) to find
 trace IDs. Defaults to true

 A value of 0 will disable the timeout completely. Defaults to 11s.
