Not per se, meaning, it does not offer a special function labeled as such. However, for the works available in PDF format, there are ways you can do this.

Download the work in PDF.

Open the file on your computer.

Then use the "find" function in Adobe.

Type in a few words, and you'll be taken systematically to every time those words appear in the text. Then you'll have to scroll around a bit to find out exactly where you are in the work—what chapter, or in the case of a Shakespeare play, what act and scene.
