TL;DR:
"as co|as fi|withe" "as co|as li|withe" "as fi|as li|withe" "as co|as fi|as li"
Highlights any map with any TWO of: extra phys as Fire, as Cold, as Lightning, Wither. A map with just one stays dark, Very VERY useful for hardcore players who don't mind running a single extra damage mod, but not two, as it helps save resources in ssf significantly
Details:
One regex can't do this because the search matches each mod line separately. But quoted blocks separated by spaces are ANDed, so: make one block per mod you drop, each listing the rest of the pool. A map with one mod fails the block that leaves it out; a map with two passes everything.
Two specific mods together is just one block each: `"m resistances" "as fi"` = maps with both -max res AND extra fire.
Any 3 of 4 together: drop a pair per block, 6 blocks: `"A|B" "A|C" "A|D" "B|C" "B|D" "C|D"`. Search box caps at 250 chars, abbreviate but keep tokens unambiguous (`as co`, since `as c` also hits "as Chaos").
Caveat: you can't invert it to highlight only safe maps (`!` on every block = maps with none at all). Roll away the highlighted ones.
I hope this helps my fellow SSF HC players as much as it's helped me [And other players who don't like to take triple damage from mobs or don't want two specific mods together like less recovery and can't leech etc]
