Search: examples of searches to improve.

### Impacted plugin

Jetpack

### What

These are cases where we'd like to improve our search results.

### How

Just add more examples as comments on this issue. Hopefully we can gather enough of them to work through some of the more common cases.

Example:
"what version of wordpres am i using" on https://wordpress.com/support/ gives no results, but "version of wordpress" gives good results.

No files, tests, or entry points are identified. Add concrete search examples as comments, using the provided WordPress.com support example as a model; the issue is complete when enough examples have been gathered to identify common cases for later work.
