いくつかの結果を表示するために空のクエリを実行すると、そこに値があることがわかります。例:私はこのようなクエリを実行するとElasticSearchは文字列フィールドに存在する正確な値を見つけることができません

}
}
しかし、それは何も返さない:
curl -X POST http://localhost:9200/geotiff_test/geometa/_search -d '{
"query": {
"term": {
"thumbnail": "thumbnail1536.png"
}
}
}'
これが結果です:これはSolrのだったら、私がしたいすべての
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits": []
}
}
doはこの簡単なクエリを実行します:thumbnail:"thumbnail1536.png"
誰かが私にここで何がうまくいかないと教えてくれる?
私はESが本当に新しいです。だから私はSolrではクエリが文字列またはテキストフィールドのどちらかに対して機能するため、なぜそれが重要なのかわからない。 –
