# Optional: HanLP query tokenization for the main backend venv (QueryParser).
#
# Install:
#   source activate.sh
#   pip install -r requirements_hanlp.txt
#
# Why pin transformers<5:
#   transformers 5.x no longer exposes `encode_plus` on `BertTokenizer`, but HanLP 2.1.x
#   still calls it → AttributeError during `hanlp.load(...)`.
#   Use transformers 4.44+ (4.x) which remains API-compatible with HanLP.

hanlp>=2.1.0
