Sphinx's Riddle

Edit: I’ve changed the Subversion reference to Github, and it’s worth noting that Riddle works with Sphinx 0.9.8, 0.9.9 and 1.10-beta at the time of writing (January 2011). Original post continues below:

Built out of the work I’ve done for Thinking Sphinx (which has just got basic support for delta indexes, attributes and sorting – although the documentation doesn’t reflect that), I’ve extracted a new Ruby client that communicates with Sphinx, which I’ve named Riddle.

I’m not going to delve into the code here – because I’m not expecting it to be that useful to many people (and I just wrote examples in the documentation – go read that instead!) – but I’m very happy with how it’s ended up, and it’s got some level of specs to give it a thorough test. It’s also compatible with the most recent release of Sphinx (0.9.8 r871). Should you wish to poke around with it, just clone it from Github:

git clone \
  git://github.com/freelancing-god/riddle.git

It’s also being used in Evan Weaver’s UltraSphinx plugin, which I’m pretty pleased about.

hi,
Thanks for the wonderful ruby wrapper for sphinx api. I am using it on a project of mine. I won’t be using thinking sphinx because of the architecture that i have adopted. could you please clarify one simple doubt which i am somehow getting wrong. how do i use the sorting mode SPH_SORT_EXPR
i tried the following syntax but its generating error
riddle.sort_mode = :expr
riddle.sort_by = ‘@weight * page_rank DESC

thanks for your help in advance

Hi golak

I’ve not had the opportunity to use the expression sorting mode – but your syntax looks right to me. Perhaps remove the DESC? None of the examples in the documentation have that. If that doesn’t help, shoot me an email with the error stack trace, I’m happy to look into it.

Hello,
I’m newby in ultrasphinx, and i’m egtting a headache trying to use the mode :expr with RoR.
Here’s what I’m using:
#search = Ultrasphinx::Search.new(:class_names => @types, :query => "*#{query}*", :per_page => per_page, :page => @page, :weights => @weights, :filters => @query_filters, :sort_mode => 'expression', :sort_by=>['weight +trust*100 – deprecated * 10000 + rating_count * 1000 -percent_variation*100 -monetary_price’])

And i’m getting an error of SortMode invalid.

does anybody knows the way to do this?
Thanks in advance!

Hi Rodrigo

I’m not entirely sure how UltraSphinx works, but if it is just passing through the sort_mode argument to Riddle, then you want to use :expr instead of 'expression'.

Hello again, I went back on this sphinx stuff that didn’t work for me, and i’m still having this problem, it continues giving me the "Sortmode “expr” / “expression” or whatever i put INVALID.
I’m stucked with this, any comments would be appreciated.
Thanks.

Hi Rodrigo

Are you setting sort_mode as a symbol or a String? Because it needs to be a symbol. If you want to continue this discussion on the Thinking Sphinx google group, then we can discuss this further, and with code examples.
