When searching continueAsNew, one of the last results is:

https://typescript.temporal.io/api/namespaces/workflow/#continueasnew

Describe the solution you'd like

It would be nice if it were first. It looks like the two ways to rank things higher are recordProps.lvl*:

https://docsearch.algolia.com/docs/templates#docusaurus-v2-template

or pageRank, which is by index / pathsToMatch:

https://docsearch.algolia.com/docs/record-extractor#boost-search-results-with-pagerank

with which we could have a separate rank for /api/namespaces/*, or put functions to their own dir, like /api/functions/workflow.
