无法使用Firebase和ElasticSearch(使用Flashlight)进行正确的路径监控或查询
eiv*_*dml 11 json heroku node.js elasticsearch firebase
我正在尝试将ElasticSearch与Firebase集成.我正在使用Firebase中的Flashlight集成来全部设置.我已经将代码部署到Heroku,如上面链接的Github repo中所述.
它的工作原理是,当我插入查询对象时,/search/request/我得到一个/search/response结果.但结果有点乱,不正确.但我无法弄清楚出了什么问题.
这是config.js我定义要监视的路径的位置:
/** 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(它位于根目录下).
"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,并返回最佳结果.我真正需要的只是用户名和用户ID.
但是当我用上图中的对象查询时,我得到下面的响应:

哪一个:
- 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,它看起来像是以随机顺序返回所有用户.
- B)反应非常混乱.在
/response那里有三个节点query,type并且index都包含很多点击.
那么,谁知道什么是错的？如何创建查询或制作路径监视器以使搜索起作用？也许得到一个更简单的回应？

Flashlight实际上在search/requests/$ key中查找请求,其中应包含具有字段类型,索引,查询的文档.它在搜索/响应/ $键的响应中显示结果.如果要通过手动添加密钥进行测试,请尝试将请求放在另一个节点下,例如search/requests/testkey123.
