I've been using the preview for a few months, it works pretty well. That said, one thing I miss from the regular code search feature is the ability to use a form to filter search results, or to refine results using suggested filters after an initial search. The regular search results page usually has a few pre-set choices that you can quickly click on to refine the results, like a list of languages found. Code Search supports many such filters[1], and even supporting suggestions or completion in the search box would be a good improvement. With the new UI once you're on the search results page the examples of the home page are no longer visible, so I never know if I should use lang:py or language:python, or if it's path:*.txt or filetype:txt.
