Customize indexing

The indexing process requires mapping data from an external source (database or file) to index fields to create index records or index documents. Depending on the complexity of the source data and index schema design, preprocessing the data might be required. Otherwise, indexing can be directly performed by using either the Data Import Handler (DIH) to index data from the database, or Solr APIs to index data from a file.

• Indexing an extension index using Index Load
  Index Load is an indexing service that uses the Data Load framework to load data in parallel into one or more search extension indexes.
