File search on instantOS
The default file explorer in instantOS is gnome’s nautilus. It comes with an excellent file search engine that can be accessed by just typing the search term with nautilus in focus or clicking on the magnifying glass in the top right. It searches recursively through the current directory preferring more direct matches that are higher up in the file tree. It can however slow down when searching through large amounts of files. For a faster option, see the instantSEARCH section below.
instantOS comes with a tool called instantSEARCH. It is accessed with the shortcut Super + Alt + F. It is using mlocate and plocate as a backend and works by scanning your entire hard drive first to build and index that it then searches through that index for your search term. This allows you to search through everything on your entire drive in less than a second (tested with over 500000 files on my archive HDD). This has the drawback that running it for the first time will take a while and new files only appear after scanning for changes. Re-scanning with an existing database will take considerably less time though. After opening instantSEARCH type in your search term and a list of matches will pop up. This list itself can be navigated by searching or using the arrow keys or mouse. Opening an item will bring up a file opener. The last choice on how to open a file of this type will be remembered under default, so in most cases you can just hit enter to open with your preferred program. xdg open and rifle will behave like the file is being opened in either a graphical file manager or ranger respectively. For files you also have the option to open the directory that contains the file. Choosing an option in these dialogues can be done using the usual ways or by typing the number next to the option. Past search terms and matched files are saved to grant quick access to items that are in frequent use. As an example, you close a file you’re using either to save restores or by accident and need it again, you can just open instantSEARCH and hit enter three times to open it back up.
