How to find all documents with specific string in field?(Elasticsearch) -

i have document fields:

"provider": "appstore", "device_model": "ipad3,6[graphicsdevicename: powervr sgx 554]", "days_in_game": 34, 

and need documents ipad string in device_model!

is possible?

there 2 types of search queries in elasticsearch ie. term queries , match queries. match first analyzes query string, looks documents containing words in query , returns result depending upon how closely matches. term query yes or no query , return documents have exact match. think case term query better fit. , since field not contain exact word ipad ipad3 should use prefix, wildcard or possibly regexp query depending upon document contain(take @ this)

you use following query:

{   "query": {     "prefix": {       "device_model": "ipad"      } }
