我正在使用AWS flex 搜索和以下文档来检索我的数据:
elastic search
具体来说，我在javascript中使用msearch，如下所示:
function searchElasticSearchDocument(callback) {
client.msearch({
body: [
// match all query, on all indices and types
{},
{ query: { match_all: {} } },
// query_string query, on index/mytype
{ _index: 'story', _type: 'mytypeee' },
{ query: { query_string: { query: '"this is click tj test"' } } }
]
}, function(error, response){
console.log("KKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK");
console.log(JSON.stringify(response).replace(/\\/g, ''));
console.log("eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee");
console.log(JSON.stringify(response));
});
}
我可以看到所有结果，如下所示:

但是像您一样，很难分开并仅获得所需的文档。我只需要这部分:
{
"_index": "333444",
"_type": "mytypeee",
"_id": "22",
"_score": 1,
"_source": {
"title": "mazdammm"
}
},
{
"_index": "story",
"_type": "mytypeee",
"_id": "2000",
"_score": 1,
"_source": {
"title": "this is click tj test. initial phase."
}
},
{
"_index": "story",
"_type": "mytypeee",
"_id": "3121",
"_score": 1,
"_source": {
"channel_name": "qqqqqqqqthis is click tj test. initial phase.333333333333333"
}
},
{
"_index": "story",
"_type": "mytypeee",
"_id": "3140",
"_score": 1,
"_source": {

flex 搜索中有什么方法可以指定我只需要返回我的文档，或者如果有人可以提出一种很好的方法来动态解析返回的json，我将不胜感激？
最佳答案
只需使用以下命令(其中没有match_all):
client.msearch({
body: [
{ _index: 'story', _type: 'mytypeee' },
{ query: { query_string: { query: '"this is click tj test"' } } }
]
}
关于输出的格式，您可以filter the source甚至使用response filtering option过滤整个响应的所有其他部分。
