Dataset Summary

CodeXGLUE NL-code-search-Adv dataset, available at

The dataset we use comes from CodeSearchNet and we filter the dataset as the following:

  • Remove examples that codes cannot be parsed into an abstract syntax tree.
  • Remove examples that #tokens of documents is < 3 or >256
  • Remove examples that documents contain special tokens (e.g. <img ...> or https:...)
  • Remove examples that documents are not English.

Supported Tasks and Leaderboards

  • document-retrieval: The dataset can be used to train a model for retrieving top-k codes from a given English natural language query.


  • Python programming language
  • English natural language
