关于elasticsearch-py api的新手问题。我建立了一个名称,地址,电话号码等记录的索引,我可以使用python客户端进行查询 例如
`elasticsearch.search(index = "index_name", q= 'first_name:"JOHN"')`
并获得适当的结果 但是,我想将查询作为字符串参数
first_name = "JOHN"
qu = "first_name:".join(first_name)
elasticsearch.search(index = 'index_name', q = qu)
,查询失败。有没有更好的方法来进行这些类型的动态查询?

我通常会将搜索查询构建为请求正文搜索。 https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-body.html
以下示例:
searchdata = essearch.search(index=indexname, body= {
"query": {
"filtered": {
"query": {
"query_string": {
"query": "name:fred"
}
},
"filter": {
"bool": {
"must": [
{
"exists": {
"field": "fieldname"
}
},
{
"exists": {
"field": "secondfieldname"
}
}
]
}
}
}
},
"size": 5000,
"sort": [
{
"loggeddate": {
"order": "desc"
}
}
]
}
)

您是否尝试过解压缩类似的字典:
mydict = {" firstname":firstname} elasticsearch.search(index =' index_name",** mydict)
甚至:
mydict = {" index":" index_name"," firstname":firstname} elasticsearch.search(** mydict)
mydict可以拥有你需要的任何键值对
