On regular search engines, I'm as specific as possible, but sometimes I have to vary the words in the searches in order to make sure the scope of the search reaches as far back as I need it to. Most of the things I search for are to confirm that what I'm recalling from old news articles 20 or more years ago, are correct. Does Grok provide sources from old news article?
I spent many years doing historical research. It wasn't my job, but research I was interested in. It was very exciting, because you never knew what you'd find after you opened a box of documents, or where it might lead you next. Another wonderful source for info are old newspapers on microfilm. Spent many hours pouring over those too. Most of my research was on the Civil War back then.
I tried the link you provided, but I don’t do X, or any social media, so access is out of the question.
