Transaction not always displayed

This transaction is weird. It shows up with this search:
from:2020-01-15 to:2020-01-16 wallet:“IDEX “Bridge” transactions”

BUT, it doesn’t showed up withe these searches:
from:2020-01-15 to:2020-01-16
from:2020-01-15 to:2020-01-16 account:“Bittrex USD Wallet”

Is this some sort of basic mistake from my part? Or something is going on with the search engine?
