Can support text content preview?

I have used listary for a long time, and I bought genuine. Now, One of the most needed features is the preview function of text files and the content search function of text files. During the work, a lot of content will be recorded in the text. For search results, but I’m not sure if the content is what I need. I can only open it and look at it., but if I find that I don’t need it, I have to re-open the listary to search. I have to repeat this action to know that I have found the right text file. Can it support previews like Spotlight on Mac?, it’s very convenient

Try Everything for such job.
It displays a list of matches and you can enable preview to browse across all entries.
