     *                                                manipulation to search strings. Supported types are currenlty 'date'

     * @param  {Object}  filters_options              Build selects for the filters row, and pass their value.
     *                                                eg. { 1 => vendors } will build a select with the vendor list in the second column

     *                                                Expect a node in which to place the descriptions. It must have a data-prefix attribute to build the description properly.
     * @param  {Object}  aditional_search_descriptions Pass additional descriptions
