Searching the workbench

搜索工作台

In this section, you will search the workbench for Java elements.

本小节，你将在工作台中搜索Java元素。

In the Search dialog, you can perform file, text or Java searches. Java searches operate on the structure of the code. File searches operate on the files by name and/or text content. Java searches are faster, since there is an underlying indexing structure for the code structure. Text searches allow you to find matches inside comments and strings.

在搜索框中，可以搜索文件、文本和Java元素。Java元素是基于代码结构搜索的，而文件是基于文件名和文本内容搜索的，Java元素搜索更快，因为有内置代码结构的索引。文本搜索可以让你找到匹配的注释和字符串。

Performing a Java search from the workbench

搜索Java元素
