📝 Walkthrough

Walkthrough

The change standardizes FuzzyFilter on case-insensitive matching and adds score caching. Word boundaries now use letter detection. FuzzyScoreSorter ranks recursive results using the highest parent or child score. The extensions list now uses fuzzy filtering and score sorting. Shortcut and Get Started searches no longer set explicit case sensitivity.

Merge Risk: 🔵 Low · up to afd73

Fuzzy search can rank tree results by descendant matches, but large nested lists may become slow while results are sorted. The change is otherwise mergeable with awareness of this performance follow-up.

Fuzzy searching with case sensitive matching makes little sense. So let's remove the property entirely now, before the class is used outside of the framework. (Alternative: change default to Qt::CaseInsensitive)

Recognize all non-letter characters as a word boundary. This improves the palette search results for dynamics, e.g.: searching for "piano" will correctly count "p (piano)" as a full word match.

Take the score of child items into account when sorting a model with recursive filtering enabled. This places parent items with better child matches before parents with worse matches.

Add a bonus score when the pattern matches on the entire text. This bonus is higher the the word bonus.

- Don't sort children when their parent has a match - prefer parents that match over parents with only children that match
