Explain Analyze

edit

If you want to get more advanced details, set explain to true (defaults to false). It will output all token attributes for each token. You can filter token attributes you want to output by setting attributes option.

The format of the additional detail information is experimental and can change at any time

{
  "tokenizer" : "standard",
  "token_filter" : ["snowball"],
