c# - Searching across multiple address fields in Elasticsearch -

i have address saved in elasticsearch document in form of:

       "address": {           "streetaddress": "123 fake street",           "city": "san francisco",           "region": "california",           "postalcode": "94111",           "country": "united states"        }, 

how can search index using input string may contain data each of different fields. example user may search "123 fake street, san francisco" - or without comma.

would make sense tokenize search string , search each word against each of fields in questions? or somehow concatenate of 5 fields separate address field , search on that? we're using ngrams of size 2 - 12.

i had question asked here phone numbers concatenated of phone number elements 1 new field: searching phone number object in elasticsearch c#

but address situation different in how uses may search documents.

if plan on sticking elastic 5 while, _all field should satisfy requirements.

as @paige cook pointed out in comments above, _all field disabled default in elastic 6, no way of enabling on newly created indices in version. will, however, stay enabled on indices created in version 5.

if read section _all field in breaking changes documentation listed above, you'll see references query_string , simple_query_string methods (both available through nest library part of http api elastic provides) both of continue searching across fields, though _all field disabled.

hopefully 1 of these can solve issue facing.
