You cannot find "microbit.accelerometer" and similar module docs by typing "accelerometer" in Search.

It works if you type the full module name of "microbit.accelerometer" but no-one is likely to do this.

We should reconsider what (or how) we index here to improve matching microbit.* module names.

If the technical solution turns out to be too complex, a workaround could be to mention the module name in the description. for example, SPI shows up because of that (but uart, i2c, etc don't).

Some improvement was made in this PR which can be tested using the beta.

Works a treat, thanks Rob!
