Re: Ranking search results by relevancy
Alex,
Here's what you asked in your original email, and why I mentioned OR:
"Can it be done all at once in just 1 search query? or should I
compile results from 3 queries?"
These documents indicate that the default sort is descending relevancy score:
*
https://wiki.apache.org/solr/SolrRelevancyFAQ#Why_are_search_results_returned_in_the_order_they_are.3F
* https://wiki.apache.org/solr/CommonQueryParameters#sort
The relevancy FAQ link I provided has useful information and links to
other documents that should be able to give you more information about
what kinds of sorting you can do.

Hi Luke,
That was not the question... I know that I can use ORs, etc... I wanted to
know how to sort them by relevancy or higher equality score.
Thanks,

Re: Ranking search results by relevancy
Hi Alex,
You can use the HTTP search endpoint to see what information Riak
returns for Solr queries as well as to try out queries:
https://docs.basho.com/riak/kv/2.1.4/developing/usage/search/#querying
Since you're indexing first and last name, I'm not sure what indexing
a full name buys you on top of that.
It should be possible to combine your queries using OR.
More info about Solr ranking can be found online (such as
https://wiki.apache.org/solr/SolrRelevancyFAQ).

riak cs performance question
Hi I am quite new to RIAK-*. I have setup riak cs on a single server (for evaluation purposes) with adequate RAM, CPU and high performance storage. I am using Cosbench to benchmark RIAK-CS using the S3 proxy connection. Cosbench is also running on the same server (the reasons being I wanted to eliminate the effect of network on performance). I have tried different workloads (100% reads, 80:20 read write mix, number of objects (20-2), size of objects (4K-64K)). My observation has been that I have not managed to push the throughput to beyond 2.5Kops - the best case being 100% reads and about 128 objects and 128 cosbench worker threads. With 20% writes the number comes down to less than 1000. The CPU is largely idle, plenty of RAM left (order of GB). Storage is capable of 300K+ IOPS but hardly utilised. Coming to my question: does this represent the limit of performance of a *single* riak-cs node. I notice that the average response time is in the order of 60ms. Lastly, has anyone compared S3 with RIAK-CS? Thanks, -M -- View this message in context: http://riak-users.197444.n3.nabble.com/riak-cs-performance-question-tp4034341.html Sent from the Riak Users mailing list archive at Nabble.com. ___ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com

Re: riak-erlang-client
Hi Richard, Yes, sharing a riak-erlang-client connection process among multiple Erlang processes should not cause any problems. The riak_pb_socket processes are implemented using a gen_server, and they use a queuing mechanism to handle concurrent requests. If process A has sent a request and is waiting for a response, and process B tries to send a request using the same connection process, its request will get queued up and will be sent once process A's request gets a reply. Keep in mind though that this queuing mechanism could cause suboptimal performance if you have many processes competing for use of a single connection: users of the connection may end up spending a lot of time blocked, waiting for requests from other processes to finish. Depending on the circumstances, you may find that it's better to open multiple connections than to share a single connection among multiple processes.

riak-erlang-client
Guys, most of the examples I can see that riak erlang client processes cannot be shared with multiple processes. Is it safe if more processes use the same riak connection? So in other words: is riak erlang client thread-safe?
