Riak_explorer stopped working after turn on security on cluster

[AJAX DoneBy Jack]

Hello Basho,

Today I turned on security on my cluster but riak_explorer stopped working
after that.
Anything I need to check on riak_explorer to make it works again?

Thanks,

Re: How to specify dismax related parameters like qf

[AJAX DoneBy Jack]

Hi Magnus,

So you suggest to use http API right? That day I were thinking query the
internal Solr http by sending request. Could you advise what's the
difference between Riak http API and internal Solr http API? What's the
pros and cons to use them?

Thanks,
Ajax

I am very new on Riak Search, I know can add {!dismax}before query string
to use it, but don't know how to specify qf or other dismax related
parameters in Riak Java Client. Could you advise?
