ruby - How do I search words seperated by _ and . in ElasticSearch? -

-

i new elasticsearch , happy speed @ moment. still have 1 requirement haven't been able achieve.

elasticsearch seems split following text when doing indexing:

"bmw.co.uk" "apple_macbook_pro"

i searching in ruby using elasticsearch gem:

result = client.search index: 'elasticsearch_dev',                   body: {                       query: {                           "bool" => {                             "must" => {"match" => {"search_text" => {"query" => "bmw", "operator" => "and"}}},                             "must_not" => {"match" => {"search_text" => {"query" => "", "operator" => "or"}}}                           }                       },                   }

what i'm trying achieve:

when search 'bmw' or 'bmw.co', want records bmw.co.uk match.

when search 'acboo' or 'apple', want records apple_macbook_pro match.

how go achieving this?
