Description
First of all, amazing library. But, I guess the score property of result object is always zero (even when it hasn't found any matches).
Example:
void testFuzzy() {
final fuse = Fuzzy(
[
Person('John', 'Doe', 29),
Person('Jane', 'Doe', 32),
Person('Peter', 'Parker', 36),
Person('Bruce', 'Wayne', 30),
Person('Clark', 'Kent', 50),
Person('Tony', 'Stark', 34),
Person('Clint', 'Barton', 35),
],
options: FuzzyOptions(
keys: [WeightedKey<Person>(name: 'firstname', getter: (p) => p.firstname, weight: 1)],
shouldNormalize: true,
isCaseSensitive: false,
shouldSort: false,
findAllMatches: false,
verbose: true,
),
);
var result = fuse.search('John');
if (result.isNotEmpty) {
result
.forEach((r) => print('${r.item.firstname} ${r.item.surname} (${r.item.age}) | score: ${r.score}'));
} else {
print('no results');
}
}
class Person {
final String firstname;
final String surname;
final int age;
Person(this.firstname, this.surname, this.age);
}
output shows:
flutter: Full text: "John", score: 0.0
flutter: Score average (final): 0.0
flutter:
Check Matches: true
flutter: Full text: "Jane", score: 0.5
flutter: Score average (final): 0.5
flutter:
Check Matches: true
flutter: Full text: "Peter", score: 1.0
flutter: Score average (final): 1.0
flutter:
Check Matches: true
flutter: Full text: "Bruce", score: 1.0
flutter: Score average (final): 1.0
flutter:
Check Matches: true
flutter: Full text: "Clark", score: 1.0
flutter: Score average (final): 1.0
flutter:
Check Matches: true
flutter: Full text: "Tony", score: 0.5
flutter: Score average (final): 0.5
flutter:
Check Matches: true
flutter: Full text: "Clint", score: 1.0
flutter: Score average (final): 1.0
flutter:
Check Matches: true
flutter:
Computing score:
flutter: John Doe (29) | score: 0.0
flutter: Jane Doe (32) | score: 0.0
flutter: Tony Stark (34) | score: 0.0
We can see that on verbose output the score is taken correctly, but when printing after search, is aways zero.
I can workaround it doing:
result.forEach((r) => r.score = r.matches[0].score);
result.sort((a,b) => a.score.compareTo(b.score));
But I'm not happy with this approach, is there a solution for this? Or perhaps I'm doing something wrong, please help.
Thanks in advance
