【问题描述】：
我将 elasticsearch javascript api 与 angularjs 一起使用。这工作得很好，但我需要通过中间件查询弹性搜索服务以过滤危险请求（删除、更新）。中间件使用“GET”，但 API 默认使用“POST”查询。
根据文档，我可以指定参数“方法”以通过 API 使用“GET”查询： API Conventions
它适用于 'POST' 但使用 'GET',"GET' 失败，我有一个错误：
Error: elasticQuery.search(...) is undefined
我该怎么办？ 'Get' 可以像下面这个例子一样处理长而复杂的查询？
这就是我尝试的方法：
return elasticQuery.search({
method : 'GET',
index: 'indexbotanic',
from: 0
size: 10,
body: {
"fields" : ["C_COLLECTIONCODE", "T_SCIENTIFICNAME", "T_SCIENTIFICNAMEAUTHORSHIP", "T_SPECIFICEPITHET", "T_KINGDOM", "T_PHYLUM", "T_CLASS_", "T_ORDER_", "T_FAMILY", "T_GENUS", "T_SUBGENUS", "T_VERNACULARNAME", "O_CATALOGNUMBER", "O_RECORDNUMBER", "O_CREATED", "O_SEX", "I_INSTITUTIONCODE", "D_DETERMINATIONID", "D_IDENTIFIEDBY", "M_IDENTIFIER", "E_RECORDNUMBER", "E_RECORDEDBY", "L_CONTINENT", "L_COUNTRY", "L_COUNTRYCODE", "L_COUNTY", "L_LOCALITY"],
"query" : {

"filter" : {

}

"term" : {
"T_FAMILY" : "lamiaceae"
}
}
]
}, {
"or" : [{
"term" : {

"field" : "E_RECORDEDBY",
"size" : 20
}
}
},
"sort" : "_score"
}
}).then(function (response) {
...
}
例如，这与 GET 一起工作：
curl -XGET 'http://localhost:9200/index/tablename/_search?pretty' -d '{
"query": {
"query_string": {
"query":"*keysearch*",
"fields": ["field1","field2","field3"]
}
}
}'
那么如何强制 api 使用 "-d '{ .... }' " 发送 get 呢？ 非常感谢
