  1. def getFilterPlan[DS <: GeoMesaDataStore[DS]](ds: DS, sft: SimpleFeatureType, filter: Filter, transform: Option[SimpleFeatureType], evaluation: CostEvaluation, requested: Option[String], explain: Explainer = ExplainNull): Seq[FilterStrategy]

    Selects a strategy for executing a given query.

    Selects a strategy for executing a given query.

    If a particular strategy has been requested, that strategy will be used (note - this is only partially supported, and should be used with care.)

    Otherwise, the query will be examined for strategies that could be used to execute it. The cost of executing each available strategy will be calculated, and the least expensive strategy will be used.
