elasticsearch - Rails Searchkick has_many indexing and searching -

i able search customer_id, name, lastname, , kids id, name, lastname , "birthdate"

the searching id must exact , is. searching names or lastname has misspelling distance 2 , works. want search kid_birthdate match exact (mispelling, distance 0)

so far whenever search birthdate results returned misspelling distance 2. don't know how search exact dates.

rails 5.1.0.rc1

elasticsearch-5.0.3

searchkick-2.2.0

class customer < activerecord::base   include searchable    def search_data     attributes.merge avatar_url: avatar.url, kids: kids   end    has_many :kids   ... end  class kid < activerecord::base     belongs_to :customer      def reindex_customer         customer.reindex async: true     end      ... end        module searchable   extend activesupport::concern    included     search_results_per_page = 10      def self.elastic_search(query, opts = { page: 1 })       # regex accept string contains digits or dates       regexp = /(\d+)|(^(0[1-9]|1\d|2\d|3[01])-(0[1-9]|1[0-2])-(19|20)\d{2}$)/       distance = query.match?(regexp) ? 0 : 2 #this calculate distance misspelling 0 digits , dates , 2 strings       options = { load: false,                   match: :word_middle,                   misspellings: { edit_distance: distance },                   per_page: search_results_per_page,                   page: opts[:page] }       search query, options     end   end end 

my index contains customer data her/his kids data. kids nested under her/his parent customer. how can force searching exact matching dates

for query:

curl http://localhost:9200/customers_development/_search?pretty -d '{"query":{"dis_max":{"queries":[{"match":{"_all":{"query":"28388","boost":10,"operator":"and","analyzer":"searchkick_search"}}},{"match":{"_all":{"query":"28388","boost":10,"operator":"and","analyzer":"searchkick_search2"}}},{"match":{"_all":{"query":"28388","boost":1,"operator":"and","analyzer":"searchkick_search","fuzziness":0,"prefix_length":0,"max_expansions":3,"fuzzy_transpositions":true}}},{"match":{"_all":{"query":"28388","boost":1,"operator":"and","analyzer":"searchkick_search2","fuzziness":0,"prefix_length":0,"max_expansions":3,"fuzzy_transpositions":true}}}]}},"size":10,"from":0,"timeout":"11s"}' 

this how index looks:
