opensearchIndexDeep() can sometimes be skipped

[naknomum]

Expected Behavior "Deep" indexing (e.g. re-indexing all Encounters under a changed MarkedIndividuals) is only done "when necessary", which is most efficient.

Current Behavior Any change to MarkedIndividual (for example, adding another encounter) will cause deep re-indexing of all encounters. this can have a slow response time.

Possible solutions

• #785 improvements might be "good enough", however additional action may be needed:
• background deep indexing
• have some way to disable opensearchIndexDeep() and use opensearchIndex() instead
