correction with lucene elasticsearch

I'm a newbie in Lucene Elasticsearch. I don't know how to deal with it. In documentation, I didn't found what I'm looking for.

I do have a text and it contains some misspelling wrong words that I want to correct via a large database containing correct words.
As I do have a big database, I thought about Lucene Slasticsearch for the quick research in the database.

Question

I know we use Lucene Slasticsearch for search and indexation but I don't know if we can do a research with a wrong word and it returns the correct words which are "similar" of the wrong one.

Thank you.

Solution

It would be helpful if you could mention how are you defining a word to be similar, for example just based on spelling or phonetically.

Assuming you want to do just a spelling-based correction, the best approach is using custom analyzers, and Elasticsearch has a whole bunch of options for that. https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-analyzers.html https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-custom-analyzer.html

What you need to do is:

First decide on what type of filter and tokenizer you want to use.
Then add the analyzer in your index settings.
Then add the analyzer in your mapping.
