How can I view the contents of an ElasticSearch index

Question

I configured a custom analyzer and put some documents into the index  Now I want to debug my settings so I can see which n-grams actually made it into the index   When I used Solr before  there was a possibility to see which strings were saved in the index as keys and also their frequency

If you didn t index too much data into the index yet  you can use term facet query on the field that you would like to debug to see the tokens and their frequencies   curl -XDELETE  http   localhost 9200 test-idx  echo curl -XPUT  http   localhost 9200 test-idx  -d          settings              index number of shards    1           index number of replicas   0             mappings                          doc                  properties                      message     type    string    analyzer    snowball                                     echo curl -XPUT  http   localhost 9200 test-idx doc 1  -d        message    How is this going to be indexed       echo curl -XPOST  http   localhost 9200 test-idx  refresh  echo curl -XGET  http   localhost 9200 test-idx doc  search pretty true amp search type count  -d         query              match                   id    1                        facets              tokens                  terms                      field    message                                    echo
