+You can use the npm search bar to find packages to use in your projects. The search is performed using content from the package's title, description, readme, and keywords and is powered by [opensearch](https://opensearch.org/). Search results are displayed based on keyword matching from the package's title, description, readme, and keywords. No subjective ranking criteria are applied, except for a minimal boost to deprioritize spammy or entirely new packages, aiming to maintain a neutral stance towards all other packages.
 
 ## Searching for a package
 
 1. In the search bar, type a search term and press **Enter**. As you type, possible choices will appear.

-## Package search rank criteria
-
-Often, there are dozens or even hundreds of packages with similar names and/or similar purposes. To help you decide the best ones to explore, each package has been ranked according to four criteria using the npms analyzer:
-
-### Popularity
-
-Popularity indicates how many times the package has been downloaded. This is a strong indicator of packages that others have found to be useful.
-
-### Quality
+   <Screenshot src="/packages-and-modules/getting-packages-from-the-registry/search-sort-options.png" alt="Screenshot of the search Sort by dropdown featuring sorting options" />
 
-Quality includes considerations such as the presence of a README file, stability, tests, up-to-date dependencies, custom website, and code complexity.
-
-### Maintenance
-
-Maintenance ranks packages according to the attention they are given by developers. More frequently maintained packages are more likely to work well with the current or upcoming versions of the npm CLI, for example.
-
-### Optimal
-
-Optimal combines the other three criteria (popularity, quality, maintenance) into one score in a meaningful way.
