For example, when I wanted to install a search engine about which I just knew that it was a Metasearch engine that protected its customers’ privacy, I found it really useful. However, because I couldn’t recall the name of that search engine, I typed in the following search term:

$ sudo apt-cache search “metasearch engine”

When the results were displayed, I discovered the required search engine name: “Searx.” After that, I simply installed it using the apt install search command.

Similarly, if we use the show flag with apt-cache, it will display basic information about the package, such as its version, size, dependencies, description, and so on. Use the display flag to get details on a certain package:
