所以我最终设置了elasticsearch数据库并将数据导入其中。
有时当我尝试从前端请求数据时，我得到500错误（不是所有时间，有时候）。
我尝试从POSTMAN请求数据（查看ES错误消息）。
我得到了：

"status": 500
}
以下是请求正文：
{
"query": {
"function_score": {
"query": {
"multi_match": {
"query": "test",
"minimum_should_match": "-25%",
"type": "cross_fields",
"tie_breaker": 0.5,
"fields": ["title^3", "body", "url_words^2", "domain_words^8"]
}
},
"functions": [{
"field_value_factor": {
"field": "rank",
"factor": 1
}
},{
"field_value_factor": {
"field": "lang_en"
}
}]
}
},
"from": 0,
"size": 25
}
我知道字段[lang_en]的缺失值是问题所在。我用谷歌的结果玩弄了es，但没有成功。
ES版本：1.5.2
有什么想法吗？
编辑：
我添加了“missing”：0，到第二个field_value_factor，但我收到了此错误：

在至少一个文档中，字段lang_en为空，空或根本不存在。
你需要修改你的field_value_factor函数，以告诉它在这种情况下要做什么，使用missing设置，无论默认值是否合理（0,1等）：
{
"field_value_factor": {
"field": "lang_en",
"missing": 1 <---- add this line
}
}

问题在于愚蠢的AWS ES版本1.5.2。
我的解决方案：创建EC2实例并手动部署Elasticsearch。
