【问题描述】：
我正在尝试将 ElasticSearch 与 Firebase 集成。我正在使用来自 Firebase 的 Flashlight integration 进行设置。我已按照上面链接的 Github 存储库中的描述将代码部署到 Heroku。
从某种意义上说，当我向/search/request/ 插入查询对象时，我得到/search/response 结果。但是结果有点乱，不正确。但我不知道出了什么问题。
这是config.js 中定义的内容，我在其中定义了要监视的路径：
/** Paths to Monitor
*
* Each path can have these keys:
* {string} path: [required] the Firebase path to be monitored, for example, `users/profiles`
* would monitor https://<instance>.firebaseio.com/users/profiles
* {string} index: [required] the name of the ES index to write data into
* {string} type: [required] name of the ES object type this document will be stored as
* {Array} fields: list of fields to be monitored and indexed (defaults to all fields, ignored if "parser" is specified)
* {Array} omit: list of fields that should not be indexed in ES (ignored if "parser" is specified)
* {Function} filter: if provided, only records that return true are indexed
* {Function} parser: if provided, the results of this function are passed to ES, rather than the raw data (fields is ignored if this is used)
*
* To store your paths dynamically, rather than specifying them all here, you can store them in Firebase.
* Format each path object with the same keys described above, and store the array of paths at whatever
* location you specified in the FB_PATHS variable. Be sure to restrict that data in your Security Rules.
****************************************************/
exports.paths = [{
path: "users",
index: "firebase",
type: "user"
}, {
path: "messages",
index: "firebase",
type: "message",
fields: ['msg', 'name'],
filter: function(data) {
return data.name !== 'system';
}
}];
这是 Firebase 中用户节点的结构（位于根目录）。
"users" : {
"userid123" : {
"friends" : {
"userid42" : 1
},
"recs" : {
"-recid1234" : 0
},
"user_info" : {
"createdAt" : 1475157596,
"email" : "e@male.org",
"name" : "Firstname Lastname Johnson",
"profilePicture" : "png.jpg",
"pushId" : {
},
"username" : "userLooser"
}
},
"userid42" : {
"friends" : {
"userid123" : 1,
"test1" : 1
},
"recs" : {
"-recid5678" : 0
},
"user_info" : {
"email" : "email@icloud.com",
"name" : "Firstname Lastname",
"phoneNumber" : "",
"profilePicture" : "jpg.png",
"pushId" : {
},
"username" : "userName"
}
}
}
}
我想要实现的是搜索用户名，并返回排名靠前的结果。我真正需要的只是用户名和用户 ID。
但是当我使用上图中的对象进行查询时，我得到了下面的响应：
"search" : {
"response" : {
"index" : {
".priority" : 1.477326417519E12,
"hits" : [ {
"_id" : "test1",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
"test1" : 1
},
"recs" : {
},
"user_info" : {
"createdAt" : 1475157596,
"name" : "Testbruker 1",
"username" : "testuzer"
}
},
"_type" : "user"
}, {
"_id" : "userid123",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
},
"recs" : {
},
"user_info" : {
"email" : "",
"name" : "Firstname Lastname",
"phoneNumber" : "",
"profilePicture" : "",
"pushId" : {
},
"username" : "profileName"
}
},
"_type" : "user"
}, {
"_id" : "userid42",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
},
"recs" : {
},
"user_info" : {

"pushId" : {
},
"username" : "userLooser"
}
},
"_type" : "user"
} ],
"max_score" : 1,
"total" : 3
},
"query" : {
".priority" : 1.477326417484E12,
"hits" : [ {
"_id" : "test1",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
"test1" : 1
},
"recs" : {
},
"user_info" : {
"createdAt" : 1475157596,
"name" : "Testbruker 1",
"username" : "testuzer"
}
},
"_type" : "user"
}, {
"_id" : "userid42",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
},
"recs" : {
},
"user_info" : {
"email" : "",
"name" : "Firstname Lastname",
"phoneNumber" : "",
"profilePicture" : "",
"pushId" : {
},
"username" : "profileName"
}
},
"_type" : "user"
}, {
"_id" : "userid123",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
},
"recs" : {
},
"user_info" : {
"createdAt" : 1475157596,
"email" : "e@male.org",
"name" : "Firstname Lastname Johnson",
"profilePicture" : "",
"pushId" : {
},
"username" : "userLooser"
}
},
"_type" : "user"
} ],
"max_score" : 1,
"total" : 3
},
"type" : {
".priority" : 1.477326417503E12,
"hits" : [ {
"_id" : "test1",
"_index" : "firebase",
"_score" : 1,
"_source" : {
"friends" : {
"test1" : 1
},
"recs" : {
},
"user_info" : {
"createdAt" : 1475157596,
"name" : "Testbruker 1",
"username" : "testuzer"
}
},
"_type" : "user"
}, {
"_id" : "userid42",
// Same content as above
}, {
"_id" : "userid123",
// Same content as above
} ],
"max_score" : 1,
"total" : 3
}
}
}
其中：
- A) 不返回正确的排序。第一个结果与我的搜索查询完全不匹配，看起来它以随机顺序返回所有用户。
-
B) 回复真是乱七八糟。在
/response下有三个节点query、type和index都包含很多的命中。
那么，有谁知道怎么回事？如何创建查询或制作路径监视器以使搜索正常工作？也许得到一个更简单的回应？
