Create Custom Elasticsearch Index Settings (Optional)

If the Elasticsearch index settings that Informatica provides do not meet your requirements, you can create custom index settings. The custom index settings must include analyzers, which convert text into tokens or terms that are added to the inverted index for searching.

An analyzer must have only one tokenizer, and can have zero or more character filters and token filters. Tokenizers receive a stream of characters that are converted into tokens. Token filters receive a stream of tokens generated by a tokenizer and might add, remove, or change tokens. Character filters receive a stream of characters and can add, remove, or change characters in the stream.

The tokenizer, token filters, and character filters that you use in a custom analyzer can be the Informatica default, custom, or Elasticsearch built-in components. You cannot edit the default settings. When you configure an analyzer, the Elasticsearch built-in tokenizers and token filters are available for selection.

For more information about Elasticsearch index settings, see the Elasticsearch documentation.
