for doc search, i want the following enhancements, please:

- while the docs are being searched and coming up, i want to know this is happening (it just shows empty result set rn)
- the search should be faster (currently like 5 seconds)
- improve the searching (currently "markdown" returns a lot of results, but the markdown renderer doc is not near the top. if the term is in the title, that title should be near the top)
