How to make Sphinx filter on negative values?

Question

PHP

Good afternoon!
On one of the projects, I decided to use Sphinx to build filtering, sorting and searching for goods. Everything was fine, but then there was a problem, one of the parameters, which is displayed on the front as a range slider, can take negative values. When building a config, I use this property as sql_attr_uint and, as the name implies, the field can only contain positive integer values. As a result, the filter began to fail, after a little searching, I realized that it would not be possible to set a negative number in sphinx, much less to filter by it. How to be in such a situation? I use the PHP sphinx library, but I will consider the option on the usual SphinxQL

Answer 1

Isn't sql_attr_bigint suitable? Judging by the documentation, this type is signed.
