Modifier and Type	Method	Description
`ReadCommand`	`command()`	Returns the `ReadCommand` for which this searcher has been created.

- Method Detail
  - command
```
ReadCommand command()
```
    Returns the ReadCommand for which this searcher has been created.
    
    Returns:
    
    the base read command
  - search
```
UnfilteredPartitionIterator search(ReadExecutionController executionController)
```
    Parameters:
    
    executionController - the collection of OpOrder.Groups which the ReadCommand is being performed under.
    
    Returns:
    
    partitions from the base table matching the criteria of the search.
  - filterReplicaFilteringProtection
```
default PartitionIterator filterReplicaFilteringProtection(PartitionIterator fullResponse)
```
    Replica filtering protection may fetch data that doesn't match query conditions. On coordinator, we need to filter the replicas' responses again. This will not be called if Index.QueryPlan.supportsReplicaFilteringProtection(RowFilter) returns false.
    
    Returns:
    
    filtered response that satisfied query conditions
