Is there any possibility to make a search on two non-complete words in the same field using Elasticsearch in Rails? I mean the situation when I could successfully search for example "victorian buildings" phrase by inserting into search input for example "vict bui" phrase (only beginnings of words, also with fuzziness).

Partial match (word_start, text_start etc. available in Searchkick) doesn't work in this project. I've also tried using wildcard queries, but it also failed. Maybe writing some custom mappings/settings would be a good idea?

Can I ask you for any suggestions on what to search/read to do this task?

  • Can you update your question to explain why partial match doesn't work? `word_start` is designed for this use case. – Andrew Kane Aug 09 '18 at 07:53

Try this example


"%#{params[:place]}%"


Since % is a wildcard, doing a like on '%%' matches everything,

and you get all the records in the result.
