Thanks Sean for the hint .. sure, you right, that wildcard syntax was too
short !
Still like this, the main issue remains. The search function is not yet
activated at the server side, even having the parameter set to true in
the /etc/app.config file. Whatever syntax sent to the server is not
checked, nor validated, nor executed. I've restarted the server with
bin/riak stop and bin/riak start .
The same error also shows up at the sample bucket 'user' throwing 0
results (with no error message). I'm using the git version built from
source.
at rel/riak/etc/app.config
%% Riak Search Config
{riak_search, [
%% To enable Search functionality set this 'true'.
{enabled, true}
]},
Any further settings required to activate the server-side search function?

Subject: Re: Riak / Search via Python Client, no Results from
Server
Claude,
Generally your terms in wildcard queries need to be at least two or three
characters (I don't remember which), so either way A* is not going to work
as a search.

Dear colleagues.
Not able to run a pattern search through the Python query. The server
search option was enabled with the true setting in the app.config file
(line 165) and the server was restarted. Checking the Riak console log
below, I see the search being started, but no results are returned to the
client. My version is "git" built from source.

Source code: Read all data starting with Capital Letter A, cEDO is the

try:

data_bucket = client.bucket(bucketname)
mykeys = data_bucket.get_keys()

print "result entries found: " + str(len(resultset))
Processing log:
How many keys in the bucket: 500
search query built
result entries found: 0
No further error message is thrown.
ps .. Also the basic sample from the Python client documentation (bucket=
'user') shows the same results, 0 entries found by the serach.

Thanks in advance for your insights. What's missing to start the Search
feature, or is something missing in the Lucene syntax ?
