High-Traffic Live Search with Fuzzy Matching, Synonyms & Out-of-Stock Sorting
I need a lightweight live search system for a high-traffic WooCommerce website.Main requirements:Live search should work fast even during high traffic without creating pressure on the database or server.Search must use an indexed/cache-based system, not heavy real-time product queries on every keystroke.Out-of-stock products should not be hidden, but they should automatically appear at the bottom of search results.Search should support synonyms, related keywords, and common misspellings.Example: if a customer searches with a wrong spelling or alternative name, the correct products should still appear.Admin should be able to manually add synonym keywords for products, categories, brands, and tags.Search history/logs should be available in the admin panel so we can see what customers are searching for.Search history should be lightweight with auto-cleanup, for example keeping only the last 15/30/60 days, so it does not make the database heavy.The system should support high traffic with debounce, minimum character limit, caching, and rate limiting.Product indexing should run in background batches, not during customer search.It should be compatible with WooCommerce stock status, product title, SKU, category, brand, tags, and custom keywords.It should not change the website design or customer flow unless enabled from settings.It should include admin settings to enable/disable live search, fuzzy search, synonyms, misspelling correction, search logs, and out-of-stock bottom sorting.The most important thing: the search must be fast and accurate, but it must not create extra load on the database, PHP workers, or server during traffic spikes.
