The open web has infinite documents and a monopoly query box. Your app has a finite catalogue, a keyboard that fights Thai script, and users who often know the SKU already. Analytics that copy web-search KPIs will flatter you and mislead you.
At Agent Flowcore, in-app search analytics is the practice of measuring how people query inside a product, what the system returned, whether the empty state was honest, and whether the session ended because the job was done or because patience ran out. It is not “install a heatmap on the search bar.”
A complete picture usually needs four layers: the query string (and its language), the result set (size, ranks, card design), the interaction (impressions, clicks, add-to-cart or equivalent), and the session outcome (reformulations, exits, later conversion that might have nothing to do with search).
If you cannot replay a single query from event to outcome, you do not have search analytics. You have a chart named Search.
Search submitted, results rendered, result impressed, result clicked, downstream action. Session identifiers that survive a backgrounded mobile app. Without this contract, ranking debates are theatre. Our Query Intelligence Lab spends the first fortnight here on purpose.
Navigational, exploratory, comparative, known-item, complaint-shaped. Mixed EN/TH tokens. Transliteration. Missing spaces. A taxonomy is a living list, not a slide. See also our essay on Thai tokenisation pitfalls.
Zero-result and low-result queries are often the most valuable slice in the log. They name missing inventory, missing synonyms, and missing language coverage. We wrote a longer note: When the empty state is the product.
Position one collects clicks. Card size, image, and badge collect more. A ranking “win” can be a layout change. Read The click gap between rank 1 and rank 3 before you ship another feature weight.
Cluster operations, shard counts, and vendor bake-offs. Those are real jobs; they are not this studio. We also do not teach you to scrape competitor SERPs. In-app search is your catalogue talking to your users. The competitive question is usually merchandising, not PageRank cosplay.
