Specify Label search on /json/ webservice

(from github.com/AdeelIlyas2014)
How I can specify the fields.label to search for only label related documents in /json/ provided webservice?

(from github.com/AdeelIlyas2014)
I have got it working as following:

q=(sponsoring)%20AND%20label:“blogs”

Let me know if there can be any improvement in it. Thanks

field.label is a request parameter.

 q=sponsoring&fields.label=blogs

Sorry it was not working your suggested way. Please check again - there must be some bug then

For search ui it is a request parameter but for json service it is not. I checked your code of QueryStringBuilder.java. It is also saying same.

It works. The source code is here.

curl "http://search.n2sm.co.jp/json/?q=fess"
curl "http://search.n2sm.co.jp/json/?q=fess&fields.label=lucene"
