How do you search, and what do you index?

search, For example, 'aa\_bb\_cc'  
[https://github.com/aparo/pyes](https://github.com/aparo/pyes), I do this

q = TermQuery("name", "aa\_bb\_cc")  
conn.search(query = q)  
NOW,it's other errors. thanks for you.

I test this problem:  
curl -XGET [http://localhost:9200/permission/permission-type/\_search](http://localhost:9200/permission/permission-type/_search) -d '  
{ "query" : { "wildcard" : { "name" : "\*" } } }  
' && echo  
{"\_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":12,"max\_score":1.0,"hits":[{"\_index":"permission","\_type":"permission-type","\_id":"department\_set\_hr","\_score":1.0,  
"\_source" : {"codename": "department\_set\_hr", "name":  
"\u7f16\u8f91\u90e8\u95e8"}},.......]}}

curl -XGET [http://localhost:9200/permission/permission-type/\_search](http://localhost:9200/permission/permission-type/_search) -d '  
{ "query" : { "term" : { "codename" : "department\_set\_hr" } } }  
' && echo  
{"\_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max\_score":1.6931472,"hits":[{"\_index":"permission","\_type":"permission-type","\_id":"department\_set\_hr","\_score":1.6931472,  
"\_source" : {"codename": "department\_set\_hr", "name":  
"\u7f16\u8f91\u90e8\u95e8"}}]}}

It is no problem.
