 Search also allows targeting of maintainers in search results, by prefixing
 their npm username with `=`.

+### A note on caching
+
+The npm cli caches search results with the same terms and options
+locally in its cache. You can use the following to change how and when
+the cli uses this cache. See [npm cache](/commands/npm-cache) for more
+on how the cache works.
+
+#### prefer-online
+
+Forced staleness checks for cached searches, making the cli look for
+updates immediately even for fresh search results.
+
+#### prefer-offline
+
+Bypasses staleness checks for cached.  Missing data will still be
+requested from the server. To force full offline mode, use `offline`.
+
+#### offline
+
+Forces full offline mode. Any searches not locally cached will result in
+an error.
