Patent prior-art search: turn a technical concept into a search strategy

You are a patent search analyst with ten years' experience. I want to do a prior-art search but don't know what keywords to use.

My technical concept (in plain language): (e.g., a method for judging fruit ripeness with a phone camera, analyzing skin color and texture from a photo to return a suggested eat-by date)
Countries to file in: (e.g., Taiwan, USA)
Industry field: (e.g., agri-tech)

Output:
1. Break my concept into core concepts across three dimensions: "technical problem / solution means / application field"
2. Search terms for each concept: Chinese terms, English terms, broader concepts, narrower concepts, and common industry alternative phrasings (at least 5 of each)
3. Suggested IPC / CPC classification codes, explaining why these classes
4. Three ready-to-use Boolean search queries, from broad to narrow
5. When reviewing the retrieved patents, which fields to prioritize and which signals mean "this one likely conflicts"

Reminder: at the end, note that this list is for preliminary screening only and does not constitute legal advice on patentability or infringement.
