Describe the feature you'd like to request

Nextra's default search isn't very good and people are only able to sort by title. We should implement Algolia Docsearch

Describe the solution you'd like

• I've already submitted an application to the doc search program, so hopefully we get out index and key soon
• Update current search component to use algolia's doc search library. It should be a button that looks like an input for a11y that launches the algolia search popup

• The implementation can be lifted out of Formik's docs here:
  https://github.com/jaredpalmer/formik/blob/master/website/src/components/Search.tsx#L38-L91
• Additional work is needed to index the documentation properly
