Developed experimental Full-Text Search (FTS) index syntax support for synced databases in the tursodatabase/turso repository, focusing on feature parity and enhanced search capabilities. The work involved exposing an experimental_index_method on the Sync Builder, mirroring the behavior of the local Rust Builder by integrating the flag into the embedded engine through experimental_features. This enabled the CREATE INDEX … USING fts(...) syntax for synced databases, aligning the interface across different builders and improving maintainability. Utilizing Rust and database management expertise, the developer ensured downstream impact tracking and prepared the codebase for broader adoption, with an emphasis on stability and consistency.
