Make variables more descriptive of the state they represent

- Move checking if there is a prev compare string char match into function
- Move updating of index list when a better match is found for the first substring logic into function

- Moved if statement that checks if all query substrings are matched into a funciton
- convert into shorthand expression the if statement that checks if all words are fully matched

1. Remove the github repo reference as we have mixed in substring matching
2. Added context on how the logic is run

 occurs when query contains more than one whitespace eg. 'sql  manag'

Failed if query text is 'sql servman'- returns true when should be false
- moved it up so evaluation is included in the final substring check

checking if all substrings contained in compareString

Not necessary to have and not needed to add another dimension to the scoring

Two scoring changes only as a result of substring matching.

makes more sense and less conversion to int for actual precision score
