Interface MassIndexer

  • public interface MassIndexer
    Component to rebuild the indexes from the existing data. This process starts by removing all existing indexes, and then a distributed task is executed to rebuild the indexes. This task can take a long time to run, depending on data size, used stores, indexing complexity.

    While reindexing is being performed queries should not be executed as they will very likely miss many or all results.
