How the search reads a sentence

“a backpack under $25 that ships from the US and arrives this week”

ItembackpackPrice≤ $25Ships fromUSArrivesthis week
Three of these are gates the index can check. The dashed one cannot be measured, so it is shown as not measured rather than dropped. The cheapest that fits is the lowest price that passes every gate.
Why it matters here

At Vessim.

If you say “a backpack under $25 that ships from the US”, the answer is the cheapest backpack that is under $25 and ships from the US. If nothing meets every requirement, Vessim says so rather than handing you a near miss. The cheapest listing overall is often useless, because it may ship from a country you excluded or break your budget, so the two are shown together and the gap between them is the thing worth knowing.
