The present application generally relates to search engines, and more specifically to systems and methods for a search tool for code snippets. Embodiment described herein provide a customized code search system that generates code search results from customized data sources, extract code snippets from the code search results, and presents the code snippets via a user interface. In one embodiment, the search system adopts a machine learning module to generate and highlight search results from different data sources that include code examples, e.g., in a programming language. To improve search efficiency, in response to a code search query, the search system may extract code snippets from search results from relevant sources in a user interface element, such as user selectable panels.
