# Exa Reliability Patterns ## Overview Production reliability patterns for Exa neural search. Exa-specific failure modes include: empty result sets (query too narrow), content retrieval failures (sites block crawling), variable latency by search type, and 429 rate limits at 10 QPS default. ## Instructions ### Step 1: Query Fallback Chain ```typescript import Exa from "exa-js"; const exa = new Exa(process.env.EXA_API_KEY); // If neural search returns too few results, fall back through search types async function resilientSearch( query: string, minResults = 3, opts: any = {} ) { // Try 1: Neural search (best quality) let results = await exa.searchAndContents(query, { type: "neural", numResults: 10, ...opts, }); if (results.results.length >= minResults) return results; // Try 2: Auto search (Exa picks best approach) results = await exa.searchAndContents(query, { type: "auto", numResults: 10, ...opts, }); if (results.results.length >= minResults) return results; // Try 3: Keyword search (different index) results = await exa.searchAndContents(query, { type: "keyword", numResults: 10, ...opts, }); if (results.results.length >= minResults) return results; // Try 4: Remove filters and broaden const broadOpts = { ...opts }; delete broadOpts.startPublishedDate; delete broadOpts.endPublishedDate; delete broadOpts.includeDomains; delete broadOpts.includeText; return exa.searchAndContents(query, { ...
