Unexpected search result on partial word

[Nicolas-Menettrier]

If you go to the test website https://praveenn77.github.io/docusaurus-lunr-search-demo/ and write "tuto" in the search bar you will get 3 results but if you write tutoria you will only get 1 results display (back to 3 results if you write the whole word). I got the same kind of issue in my application. Is this the normal behavior of the search ?

Can confirm that issue. Also, if completing the word 'tutorial' then all 3 appear.
