Document binary files in Elasticsearch index are only for newly updated files
The following discussion from !99 (merged) should be addressed:
@terrichu : !99 (comment 504141366) :
only newly indexed or recently updated blobs will be indexed with this change correct?
@changzhengliu : Very good question! I believe it will only include the new and updated blobs. Please let me know whether/how we want to backfill the data.
@DylanGriffith : I think we should document this on the integration docs as it might be confusing. We will also need to be aware that this may lead to support requests when certain binary files can't be found.
