Hi All, I am using a different index for field abbreviations and its descriptions. How to use that index on another index to change field value based on abbreviations. Simply I am asking that one index hold US state abbr. and its full name. How to change or use this index on populating another index that using these abbr. short forms. ---

You probably want the Elasticsearch filter for that purpose [https://www.elastic.co/guide/en/logstash/current/plugins-filters-elasticsearch.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-elasticsearch.html) ---
