exa.ai/search and perplexity, and most other search engines if you put the special characters in quotes. you could also find/make an instance of searx or search across aggregators. https://searx.space/
Thank you for the suggestions. Excluding false positives and the typical hallucinations LLMs exhibit, exa.ai was useful and would often give me what I asked for. Perplexity, not as much. Searx seems interesting; I will certainly toy with it.
