@adriancole I just created an issue to document the feature. The problem was that whenever we try searching using tags(if traces are indexed by the given tag) there are no auto-populate hints as in dropdown. This PR is to allow the required data to be indexed and stored which would be used to support this feature.

makes sense, we have the same feature and same concerns. because elasticsearch is so easy to overload, we also have a limiter as writing same tag many times increases index pressure https://github.com/openzipkin/zipkin/tree/master/zipkin-storage/elasticsearch#autocomplete-indexing

We handle this by flushing the documents to ES at a regular interval (configurable). This handles duplicate documents and reduce the indexing pressure. Do note that tags(or what we call as whitelisted index fields) having 'showValues' enabled, goes into a different ES index for this autocomplete feature.
