Code Search Based on Alteration Intent
IEEE Access, 2019 Code search is to retrieve the method according to the user needs. Many people think of the query as the only one to reflect the user needs. So they start with the query and find the synonyms, semantically similar to the query terms, for query expansion.

Improving automatic query expansion [PDF]
Proceedings of the 21st annual international ACM SIGIR conference on Research and development in information retrieval, 1998 Most casual users of IR systems type short queries. Recent research has shown that adding new words to these queries via odhoc feedback improves the retrieval effectiveness of such queries. We investigate ways to improve this query expansion process by refining the set of documents used in feedback. We start by using manually formulated Boolean filters

Cluster-based query expansion [PDF]
Proceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval, 2009 We demonstrate the merits of using document clusters that are created offline to improve the overall effectiveness and performance robustness of a state-of-the-art pseudo-feedback-based query expansion method -- the relevance model.
