- "What to avoid on a limited budget: Algolia — starts free but escalates quickly into $300–$500+/month" (DeepSeek V4 Flash, budget prompt, hard negative)

- "Limited advanced merchandising — Strong on search basics, but users note gaps in complex merchandising features." (DeepSeek V4 Flash, negative prompt, soft negative)
