There we go. Finally the upgrade of thinking sphinx.

In order to deploy this we will need a fairly recent version of Sphinx.
I suggest we jump right to the latest of the 2.2 series.

Thinking Sphinx now uses app/indices for its index definitions.
It also requires some options to search to be hashes.

There's a nice upgrade documentation that i followed:
http://freelancing-gods.com/thinking-sphinx/upgrading.html
Most of it does not affect us though.

The main change was to use with_all instead of with in sphinx queries.
This way we can still have multiple constraints on the same field:
So for example to search '(1 OR 2 OR 3) AND (4 OR 5 OR 6)'

[Here](http://freelancing-gods.com/thinking-sphinx/searching.html#filters)'s
the new way of doing this:

> You can also perform combination AND and OR matches with
> :with_all using nested arrays:
>
> ```ruby
> # All pancackes belonging to tag 3 and belonging to one of tag 1 or tag 2
> Article.search 'pancakes',
>   :with_all => {:tag_ids => [[1,2], 3]}
> ```

So now we build @with in the sphinx query to be an array of arrays that
can be feed into with_all.

Before we used to send an array to thinking sphinx instead of a hash.

```ruby
Page.search 'text', :with =>
  [[:access_ids, '1 2 3'], [:access_ids, '4 5 6']]
```
