Detailed Description of the Pull Request / Additional comments

• The query term was showing up CharacterMap before Windows Terminal because the first match index in terminal was 8 whereas it was 6 for characterMap.
• To mitigate this issue, setting the first start index relative to the preceeding space. This way windows terminal gets a higher weightage as the first match index is now 0.

Validation Steps Performed

• Task Manager would have previously got a low score. However, now it is higher as we are giving preference to the fact that it is the start of a new word.

Thank you @crutkas for letting me know, really appreciate it.

We’ll continue to flag stuff that could be of use. I think we all should get together and figure out plugin model too.
