Re: Riak Control
If your not directly on the server then you need to change the 0.0.0.0 to
your server actual IP address then put in https://your_ip:8069/admin in
your local browser - of course after restarting riak.

help with riak search
Is there documentation to indicate what riak search supports in search
operations.
I have been testing some searches and even looked at:
http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/queryparsersyntax.html
for some ideas.
These work:
search:search_doc(<<"searchable-dbooks">>,<<"notes:Water">>).
search:search_doc(<<"searchable-dbooks">>,<<"notes:water">>).
search:search_doc(<<"searchable-dbooks">>,<<"notes:water OR notes:Water">>).
But these don't
? seems to work at the end but not in the middle. Same with *. Why?
search:search_doc(<<"searchable-dbooks">>,<<"notes:Wate?">>) works.
But not
search:search_doc(<<"searchable-dbooks">>,<<"notes:Wa?er">>).
How would you search for "&"? maybe it is too short to be searched on
search:search_doc(<<"searchable-dbooks">>,<<"notes:&">>). In order to
index "&", I had to use "&":
Category: Water & Wetlands (W).
When an xml file is indexed, say:
0

building app using reak
It looks like search:search_doc is using riak:local_client, so it seems that if riak is to be used with an erlang app that uses search:search_doc then the erlang app would need to start in the same erl vm as when riak starts.

rebar/reltool cool!
Wow. These tools are very helpful! I was messing with make rel and was trying to work with cowboy and riak together. So I was starting riak then starting cowboy inside of riak so cowboy could talk to riak with search:searchdoc. With the previous help here, I now have cowboy as part of the release and when I do riak start, cowboy starts. awesome! Anyway, how do you make changes, i.e., I make changes to a cowboy default_handler.erl and then I have to stop riak, remove the old riak folder, do make rel again, add my test data, then riak start to test the changes. Is there a different work flow in doing this? I could just edit the default_handler and copy the beam to the rel/riak/lib/... folder.
