ThinkingSphinx & Rails 3 - How to use OR logic on attribute filter?

Question

I am trying to perform the following search as per the docs

with_delivery = "*, IF(delivery = 1 OR region_id IN (001,002,003), 1, 0) AS delivery"
Listing.search 'ipod', 
                select: with_delivery, 
                with: { 'delivery' => 1 }

However I get the following error:

 ThinkingSphinx::SyntaxError: sphinxql: syntax error, unexpected IN, expecting ',' or ')' near 'IN (001...

It seems like sphinx cannot handle the IN syntax here, but this does not make sense since it uses this in the configs.

I am not really sure how to move past this, any help or suggestions are appreciated! :)

Answer 1

IN() in Sphinx behaves a little differently to how you're using it - the first argument should be the attribute:

with_delivery = "*, IF(delivery = 1 OR IN(region_id, 1, 2, 3), 1, 0) AS delivery"
Listing.search 'ipod', 
  select: with_delivery, 
  with:   {delivery: 1}
