Search string with space in a long text in Elasticsearch

I would like to hear from anyone who has a solid structural solution for settings and mapping for an index that will have fields with long text where I can search with spaces.



According to my knowledge, field type must keywords then I can use wildcard, which is not suggested for long text because it will be expensive.



However, is it true?



Thanks,

    You should try to use match_prefix and match_phrase_prefix which should do the job.

  • Currently, I am using match_phrase_prefix and it just works without changing the mapping, however, there is a catch. When I search for "coffee b then I get "Caffee Bean ...", which is perfect but "Caffee - Bean" is the result too. Should also I use a custom analyzer? I have already tried different options that the query presents.
