Method Summary

Modifier and Type	Method	Description
void	initialize()	Initialize the index.
default void	logStatistics()	Send statistics to the logger, if enabled.

Method Detail

initialize

void initialize()

Initialize the index. For static indexes, this is the moment the index is bulk loaded.

logStatistics

default void logStatistics()

Send statistics to the logger, if enabled.

Note: you must have set the logging level appropriately before initializing the index! Otherwise, the index might not have collected the desired statistics.
