Search for phrase, even with missing letter

[mauricioklein]

Hello!

I've researched a lot about this, but can't figure out a way to do that.

I'm searching for a way to match a phrase, even if the words are not in correct order and if some letter is missing in a word (a typo, for example).

This query should be performed in all documents, so, GET _http://localhost:9200/search would be OK.

Some examples below:

Keyword: Resaurant (missing the first "t" letter)

Should match:

• Restaurant
• Restaurante
• Chinese Restaurant
• The Restaurant of Tomorrow

The most equivalent entries will have better scores, of course.

Does anyone know who can I write down this query?

Thanks in advance!

I think you have two options:

• using wildcard search at the link below (or follow Lucene Query Syntax)

• using ngram or edge ngram tokenizer for the field that you want to search on (I think it's doable)

Just found this one... another option using shingle token filter or word-ngram
