次のように、ElasticSearch インデックスに 3 つのレコードを挿入しました。
curl -XPOST 'http://127.0.0.1:9200/geoindex_test/STREET?pretty=1' -d '
{ "cityNames" : [ { "language" : "ENG",
"name" : "w bridgewater",
"raw_name" : "W BRIDGEWATER"
},
{ "language" : "ENG",
"name" : "west bridgewater",
"raw_name" : "West Bridgewater"
}
],
"id" : 1,
"streetNames" : [ { "language" : "ENG",
"name" : "cram rd",
"raw_name" : "Cram Rd"
} ]
}'
curl -XPOST 'http://127.0.0.1:9200/geoindex_test/STREET?pretty=1' -d '
{ "cityNames" : [ { "language" : "ENG",
"name" : "bridgewater corners",
"raw_name" : "BRIDGEWATER CORNERS"
},
{ "language" : "ENG",
"name" : "bridgewater center",
"raw_name" : "Bridgewater Center"
}
],
"id" : 2,
"streetNames" : [ { "language" : "ENG",
"name" : "valley view rd",
"raw_name" : "Valley View Rd"
} ]
}'
curl -XPOST 'http://127.0.0.1:9200/geoindex_test/STREET?pretty=1' -d '
{ "cityNames" : [ { "language" : "ENG",
"name" : "bridgewater",
"raw_name" : "Bridgewater"
},
{ "language" : "ENG",
"name" : "windsor",
"raw_name" : "Windsor"
}
],
"id" : 3,
"streetNames" : [ { "language" : "ENG",
"name" : "valley view rd",
"raw_name" : "Valley View Rd"
} ]
}'
そして、次のように検索を実行します。
curl -XGET 'http://127.0.0.1:9200/geoindex_test/STREET/_search?pretty=1' -d '
{
"query" : {
"match" : { "cityNames.name" : "bridgewater" }
}
}'
ElasticSearch は 3 番目のレコード (id == 3) を最良の一致として返すと考えていました (レコード 3 は「bridgewater」と完全に一致する唯一のレコードです) が、代わりに ID 1 (w bridgewater) のレコードを最良の一致として返します。私は何を間違っていますか?
