查询

curl -XGET localhost:9200/crushlings/user_profiles/_search?pretty  -d 
'{
  "query": {
    "function_score": {
      "functions": [
        {
          "gauss": {
            "dob": {
              "origin": "2015-08-08",
              "scale": "6y",
              "offset": "24y",
              "decay": 0.33
            }
          }
        }
      ],
      "query": {
        "bool": {
          "must": {
            "term": {
              "gender": "0"

获得以下错误

• 在Laravel 5+上的ubuntu 14.02上使用弹性搜索1.6，使用elasticquent作为弹性搜索的包装。
• 上面还在命令行上进行了测试，以确保没有框架或包装器错误。
