[Bug] Inconsistent search

[cdervout]

The search results are not correct.

Steps to reproduce the behavior:

1. Go to the docfx documentation : https://dotnet.github.io/docfx/index.html
2. Do a search on the word "Permission".
3. "Per" => Returns 4 results
4. "Perm" => Returns 0 result
5. "Permi" => Returns 0 result
6. "Permis" => Returns 0 result
7. "Permiss" => Returns 2 results
8. "Permissi" => Returns 0 result
9. "Permission" => Returns 2 results

=> The 2 results available in step 9 should be brought back systematically.

In addition, I sometimes get empty results even though the word is present in the index.json summary.

For example:
I enter SDK and get no results, even though the word appears in an article. The word can also be found in the index.json file.

• OS: Windows/Chrome
• Docfx version: 2.78.3

docfx using lunr.js for search backend.
I thought these search behaviors are caused by lurn.js stemmer.

There is similar issue is reported at https://github.com/olivernn/lunr.js/issues/377

Thank you
