Build Advanced Search Experiences with a Custom Query Language
summary
Claims a custom query language lets users find needles in millions of log events with a few keystrokes, implemented by writing a PEG grammar, generating a parser that turns strings into simple objects, and a print function to round‑trip queries. The demo builds a PEG grammar, parser generator, autocomplete and error reporting, and a playground that syncs inputs to the search bar so users learn by example. It reports working tradeoffs: precision and efficiency improve, onboarding cost rises.
