Search matching¶

Sam selected Abbreviations on 12 September after trying all three options with his actual profiles. Desktop search now uses Nucleo for abbreviated Preferences and folder labels, OSA typo correction and phrase-aware BM25 mail ranking. See matching details.

In Preferences, try ntfctns, prf, dark mode or sftp fingerprint. In Move, try an abbreviated folder name or a transposition. Mail search keeps exact short-body matches first, then phrases, literal terms and corrected terms. Use Best match to see relevance ordering.

To explore fictional mail in a separate workspace:

shep_demo_dir=$(mktemp -d "${TMPDIR:-/tmp}/shep-search-demo.XXXXXX")
cargo run --profile test-ui --features test-support -- \
  --demo --search-mail --persist-demo --test-state "$shep_demo_dir/state.json"

Run without fixture flags to use the normal saved profiles. Reusing the temporary directory preserves that fictional workspace's settings and mail changes.

Comparison evidence¶

Precise and Tolerant were not selected. Their branch references are retired; the completion audit retains their commits and verification.

The local benchmark used 100,000 cached messages across four accounts, 60 samples per query and at most 50 returned rows. The multiword query matched 4,132 messages. All passed the existing 50 ms budget. These are cached-query measurements, not complete input-to-screen latency or every mailbox shape.

Results currently open settings sections. Individual-control reveal, complete dynamic captions and Flutter/browser parity remain open. Mail uses only its first twelve tokens, with AND between them; wholly numeric tokens stay exact, while mixed identifiers such as S3 can prefix-match S30. Typo discovery is bounded and can omit a possible correction.
