When the empty state is the product
Zero-result queries are often treated as tracking failures. They are usually inventory, synonym, or language failures wearing an empty screen.
Essays from the search desk
Field notes, not vendor roundups. Written by instructors and occasionally by alumni with permission. English throughout; Thai examples appear where the log demands them.

Position one is not a moral victory. Card design, thumb reach, and badge colour can explain more than your new feature weight.
Tokenisation pitfalls in Thai in-app search
Missing spaces, mixed script, and English stopword lists that delete the only token that mattered.
Reformulation chains as a proxy for intent failure
Three queries and one late click is not a successful search. It is a user doing your synonym work for you.
