Weighted search on trade - sort by sum is missing best items (there are workarounds)

Hello,

Sorting by the 'sum' field when looking at the results of a weighted search sometimes does not show the best items (i.e. items with maximum weight).

For example, this search: https://www.pathofexile.com/trade/search/Crucible/7Eo0wggC5
After sorting by sum, it currently shows me an item with sum 57.74 as the top item.
Note that the search matches many (10'000+) items.

If I set a minimum sum to restrict the number of matches, it shows me better items: https://www.pathofexile.com/trade/search/Crucible/3pwP2PJI5 shows me an item with sum 87.56.
In that case there are only 263 matches.

Is this intended behavior?

If it is intended, or if fixing it is difficult, maybe you could add a warning if a weighted search returns 10'000+ matches.
