-         * Most complicated case example:
-         * We have to sort items from offset 5, limit 5, on total object count: 14
-         * The previous AND the next pages MUST NOT be impacted but fixed if needed.
-         * legend:  #<id>|P<position>
-         *
-         * Before sort:
-         * #1|P2 #2|P4 #3|P5 #7|P8 #6|P9   #5|P10 #8|P11 #10|P13 #12|P14 #11|P15   #9|P16 #12|P18 #14|P19 #22|P24

-         * Sort request:
-         *                                 #5|P?? #10|P?? #12|P?? #8|P?? #11|P??
