Search function not finding results

Bug Description
Under an older version (slate 2.3.1) typing "userec" into the page at https://zwibbler.com/docs finds the single result "useRectangleTool". Under the latest version, as we type, we get no results until "usere" and then we get many results, and when we add the character 'c' to get userec, we get no results again. You must type the complete "userectangletool" to get the result.

Probably a bug introduced in our usage of lunr.js when we went from 0.5.7 to 2.3.9 in slate 2.7.0.

I can confirm that version 2.6.1 works properly and the latest version does not.

Note if anyone is trying to reproduce it in zwibbler docs, I have reverted to that version (thanks docker!)
