While reading your Google examples, I don’t think I could parse out what you were intending as a human. Perhaps different keywords would work better?
For example, “speed work running”, were you looking to improve sprinting? (I’m not a runner, so it almost reads to me like “working fast while on a treadmill”). Reading the rest of your example, maybe “sprint workouts” would give better results?
(40+yr old guy here, Google had always worked for me, as many people had described it working for 20yr olds. Finding the right, specific enough set of keywords had always been my “trick”. Little did I realize I subconsciously generate embeddings like a LLM to Google search)
