/**
 * Converts a string to its lowercase equivalent. If the field is an array of strings, all members of the array will be converted.
 *
 * See: https://www.elastic.co/guide/en/elasticsearch/reference/current/lowercase-processor.html
 *
 * ## Example Usage
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as elasticstack from "@pulumi/elasticstack";
 *
 * const lowercase = elasticstack.ElasticsearchIngestProcessorLowercase({
 *     field: "foo",
 * });
 * const myIngestPipeline = new elasticstack.ElasticsearchIngestPipeline("myIngestPipeline", {processors: [lowercase.then(lowercase => lowercase.json)]});
 * ```
