* We can select how sphinx will order the results.
*
* We'll use SPH_SORT_EXTENDED when we want SQL like ordering, selecting the fields to order by.
* For example, the default Sphinx order returns the same order as:
*
* $sphinx->SetSortMode(\Sphinx\SphinxClient::SPH_SORT_EXTENDED, '@weight DESC, municipio ASC');
*
*
* ...where internal fields like 'weight' are prefixed by '@', while our own fields are not. We can order
* by any field that we've specified as sql_field_string or sql_attr_string in the index configuration.
*
* We'll use SPH_SORT_EXPR when we need to use some values/fields to calculate our own ranking. You can
* use Sphinx functions and expressions listed here http://sphinxsearch.com/docs/current/expressions.html
* For example, improving users' weight by adding user_karma and pageviews:
*
* $sphinx->SetSortMode(\Sphinx\SphinxClient::SPH_SORT_EXPR, "@weight + (user_karma + ln(pageviews)) * 0.1");
*
