Search result not so great on DocFX

[iamnancy07]

Before Kusto onboard to DocFX, its search results were pretty good; however, the search experience is not so good on DocFX.

For example, when I tried to search for “let”, it shows no result…….
I have to search for “let statement” to find what I am looking for…..

It seems that the word 'let' belongs to stop words(words that are very common and are not useful in differentiating between documents) defined by lunr.js
