The results of the search are shown in real time and organized by filename. Once you've made one search, this content will be shown immediately in subsequent searches thanks to the extremely fast indexing database containing file names on your computer.
A great feature of FileSearchy is that it highlights the part of the text that matches the word you used in the search bar, making it even easier to find information. Also, you can exclude the links that you don't want to appear in the search results.
The interface of the program is very simple and you can differentiate searches by tabs so that you can compare results or run different searches simultaneously.
