Process
Document collection and scope definition
Decide which documents to include and check their format and volume. This step estimates how much cleanup work is needed.
Index building and search quality tuning
Documents are chunked into an index, then search results are tuned against real questions.
Interface integration and permission setup
The search interface and admin screen are connected, with view permissions split by department.
Acceptance testing and handover
Accuracy is measured against 50 real questions and the results are documented. Staff training is provided.
