البحث النصي الكامل في PostgreSQL مقابل محرك بحث

في هذا الدرس

choose between built-in database search and a dedicated engine.

الموضوعات المخطط لها

• PostgreSQL full-text: tsvector, tsquery, GIN index, ranking; no extra service, same transaction, always consistent.
• Dedicated engine: better relevance tuning, fuzziness, facets at scale, analyzers, horizontal scale, richer features.
• Cost of an engine: another system to run, sync, secure, and back up; eventual consistency.
• Rule: start with PostgreSQL search if needs are modest (see MID-044); move when features or scale demand it.
