I am elasticsearch newbie.

I am trying to use elasticsearch to search some titles let's say books names.

From my client I am sending the user input string every 0.5 second to the server to give suggestions.

So it could be partial words and maybe typos.

What would be the best query/way to deal with that.

Any point on the right direction will be appreciated.

Thanks

// fuzzy query example but it is not answering for multiple words
return await client.search({
 index: indexName,
 body: {
   query: {
     fuzzy: {
       title: userInputSentence 
     }
   },
 },

});

  • @AmitKhandelwal you might be right but on the other hand, I think this is a common usage to get a user input string and to look for it on the titles. – barak Mar 04 '19 at 09:20

You can achieve auto-complete by adding ngram/prefix tokenizers - this will make the partial text entered to match the docs with the full length text.

update:----------

Another option is to use Elasticsearch completion suggester and Index-Time Search-as-You-Type
