Elasticsearch

1. View index settings at http://localhost:9200/index_name?pretty

2. Calculate index creation date from http://localhost:9200/index_name?pretty

    "settings": {
      "index": {
        "creation_date": "1473791401764"
   

Calculate the timestamp by removing the last 3 digits:

    >>> from datetime import datetime
    >>> datetime.fromtimestamp(1473791401)
    >>> datetime.datetime(2016, 9, 13, 14, 30, 1)

1. Fold words with accents:

    "settings": {
      "index": {
        "analysis": {
          "analyzer": {
            "word_analyzer": {
              "filter": ["asciifolding", "lowercase"],
              "tokenizer": "keyword"
            }
