Now heavily extend the reference script extensively into whatever this topic is; "Fast 9K NNUE Search Full Application" into a single python code, as "code" in this specific requirements; 'high-coding skills', 'autofill implementation', 'no-breakdowns'.

CONTENT = The content here, is based-off the description as well as it's matching topic.

Description: "An advanced iterative Q-learning NNUE search with 9K parameters and fast training."

Special Property + Directed Features: 
"""
It'll have a lichess search that'll download games from lichess on user's and train, evaluate, and FEN extract them into a single NNUE model with 9K parameters. Killer Heuristic's, and advanced Transposition Table will be evaluated to the NNUE model with neural network learning.
