UnverifiedMulti-query retrieval uses an LLM to automatically generate 3–5 semantically equivalent but differently phrased variant queries for the same question, retrieves results for each separately, and takes the union to improve recall.70% similarUnverifiedThe N+1 problem occurs when an application retrieves a set of records and then performs additional queries for associated entities; adding an index can speed up each lookup, but it cannot eliminate excessive database round trips.66% similarUnverifiedThe column order of a composite index is crucial, as the leading column determines which query patterns the index can efficiently support; an index beginning with customer_id can support queries filtering only by customer, but may not efficiently support queries filtering only by status.66% similarUnverifiedEach query first goes through validation: only SELECT or WITH statements are allowed, only whitelisted tables are permitted, a maximum of 100 MB is billed, and a maximum of 200 rows are returned.66% similarUnverifiedPerplexity's Collections feature allows users to organize related search threads into categories and set dedicated AI instructions (system prompts) for each collection.65% similar
