Thank you for asking. Just so we understand why you need this specifically, can you tell me what your use case is? Are you searching for text in all types of files across your workspace or are you searching only Java source code?
If it’s the latter, I wanted to point out that the Java specific search wizard is quite powerful, fast and would use the internal JDT index, which will work anytime you need to search for Java constructs. Of course, I do understand that sometimes, even in source, all you need is a simple text search.
