In Elasticsearch, edge n-gram divides a word into progressive tokens, starting from the begining, and adding a new letter per each token.

Is there a way to add the same logic at word level?

> "This is a sentence"

> ["This", "This is", "This is a", "This is a sentence"]

Thanks

Have a look at [Shingle token filter | Elasticsearch Guide [7.13] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-shingle-tokenfilter.html) but it's more a ngram like than a edge n gram.

Thanks for answering, David.

Yes. Shingle acts as an n-gram filter, but I'd like to make it edge n-gram style.
