Persona: Dr. Helen, environmental scientist. Has 6 months of handwritten field observations across 3 notebooks (200+ pages).
- Tagging system : Tags every page during fieldwork: #water-sample, #soil, #site-north, #site-south, #anomaly, #seasonal (see 2.14.6 / 3.15.6).
- Exact match : Needs to find a specific pH reading she wrote weeks ago. Uses Full-Text Search, types "pH 6.4". Finds the exact page instantly among 200+ pages (see 2.10.1 / 3.11.1).
- Conceptual search : Remembers writing about contamination patterns but not the exact words. Uses Topic-Based Search: "pollution levels near river." XNote finds relevant pages even though she wrote "contamination", "toxin readings", and "chemical runoff" (see 2.10.2 / 3.11.2).
- Narrowing down : Applies Tag-Based Filtering: selects #site-north + #anomaly. Now sees only the 7 pages where she recorded unusual readings at the north site (see 2.10.3 / 3.11.3).
- Combined workflow : Opens 3 of those filtered pages in AI Chat (see 2.9.2 / 3.10.2). Asks: "What patterns do you see across these anomaly readings?" Gets a cross-page analysis highlighting a seasonal trend she hadn't noticed.
- Ongoing use : Saves the search to Recent Searches for quick access (see 2.10.4 / 3.11.4). Repeats the tag-filtered search monthly as new field data comes in, tracking whether the anomaly persists.
