There are use-cases where hallucinations simply do not matter. My favorite is finding the correct term for a concept you don't know the name of. Googling is extremely bad at this as search results will often be wrong unless you happen to use the commonly accepted term, but an LLM can be surprisingly good at giving you a whole list of fitting names just based on a description. Same with movie titles etc. If it hallucinates you'll find out immediately as the answer can be checked in seconds.

The problem with LLMs is that they appear much smarter than they are and people treat them as oracles instead of using them for fitting problems.

Maybe I read too much encyclopedia, but my current workflow is to explore introductory material. Like open a database textbook and you'll find all the jargon there. Curated collection can get you there too.

Books are a nice example of this, where we have both the table of contents for a general to particular concepts navigation, and the index for keyword based navigation.
