Info

Mappings • <strong>ElasticSearch</strong> generates this mapping: { } "program" : { "properties" : { "endtime" : { "type" : "string" }, "starttime" : { "type" : "string" }, "programid" : { "type" : "string" }, "callsign" : {"type" : "string" }, "category" : { "type" : "string" }, "channum" : { "type" : "string" }, "title" : { "type" : "string" }, "description" : { "type" : "string" } } }
Override the mapping "program": { "properties": { "starttime": { "type": "date", "format": "YYYY-MM-dd HH:mm:ss" }, "callsign": { "type": "string", "analyzer": "keyword", }, "category": { "type": "multi_field", "fields": { "category": { type: "string" }, "category_term": { "type": "string", "index": "not_analyzed" } } } } }
