Fulltext Search

If you can teach Fulltext Search using a Fulltext Search dry-run, you know it. If you only know the heading, you don’t.

Keep Fulltext Search small. Sara should finish a Fulltext Search dry-run in a few lines, not a 40-line dump.

Fulltext Search exists so Sara can keep a Fulltext Search dry-run correct in a first job task.

Sara ships Fulltext Search in a first job task. That is the use case worth saying.

Don’t do this with Fulltext Search — skipping the failure case for Fulltext Search. Interviewers spot it in ten seconds.

After Fulltext Search, Sara should still remember skipping the failure case for Fulltext Search.

Close Fulltext Search with: “If I skip it, a Fulltext Search dry-run goes wrong like this: skipping the failure case for Fulltext Search.”

Exam tip

Board: a Fulltext Search dry-run. Dry-run Fulltext Search. Name the trap: skipping the failure case for Fulltext Search.

Fulltext Search — sample query

-- Fulltext Search
CREATE TABLE demo (
  id INTEGER PRIMARY KEY,
  label TEXT NOT NULL,
  qty INTEGER DEFAULT 0
);
INSERT INTO demo (id, label, qty) VALUES
  (1, 'alpha', 2),
  (2, 'beta', 5);
SELECT label, qty FROM demo WHERE qty >= 2 ORDER BY qty DESC;

Fulltext Search: create two demo rows, then SELECT qty >= 2 ordered. Say which labels come back.
