RoutingFields	addIp(String fieldName, InetAddress value)
RoutingFields	addLong(String fieldName, long value)
RoutingFields	addString(String fieldName, org.apache.lucene.util.BytesRef utf8Value)	This overloaded method tries to take advantage of the fact that the UTF-8 value is already computed in some cases when we want to collect routing fields, so we can save re-computing the UTF-8 encoding.
RoutingFields	addUnsignedLong(String fieldName, long value)
BytesReference	buildHash()	Here we build the hash of the routing values using a similarity function so that we have a result with the following pattern: hash128(concatenate(routing field names)) + foreach(routing field value, limit = MAX_ROUTING_FIELDS) { hash32(routing field value) } + hash128(concatenate(routing field values)) The idea is to be able to place 'similar' values close to each other.

buildHash

public BytesReference buildHash()

Here we build the hash of the routing values using a similarity function so that we have a result with the following pattern: hash128(concatenate(routing field names)) + foreach(routing field value, limit = MAX_ROUTING_FIELDS) { hash32(routing field value) } + hash128(concatenate(routing field values)) The idea is to be able to place 'similar' values close to each other.

addString

public RoutingFields addString(String fieldName,
 org.apache.lucene.util.BytesRef utf8Value)

Description copied from interface: RoutingFields

This overloaded method tries to take advantage of the fact that the UTF-8 value is already computed in some cases when we want to collect routing fields, so we can save re-computing the UTF-8 encoding.
