Rank exact matches higher than partial matches for paths and highlight partial matches

Feedback

When using the file:<filename> query filter, partial matches in the path are ranked higher than exact name match. Additionally, it would be valuable to highlight the matched portion of a file or directory name to make it easier to see why a result was included.

Example

search query: lang:java file:ciab
In this example, there is directory named ciab in a Perforce depot. However it is not visible until you scroll down to roughly the second page because partial matches from GitHub repositories that have more stars appear to be ranked higher.

Also, because the term ciab can show up in the middle of a file name (Associable, for example) it makes it difficult to see why a result is included when scanning. If it's not obvious, the user starts to question if the results are trustworthy. So, an additional suggestion is to highlight the partial match in the path.

Heads up @jjeffwarner - the "team/search-core" label was applied to this issue.

@mike-r-mclaughlin not a true fix, but the admin should specify a experimentalFeatures.ranking.repoScore to boost the perforce depot's results above githubs. I assume in general they want a big perforce repo to be ranked higher than github.
