Great work!

Why not use the score to order it?
Like

.Where(x=>{
x.Score = StringMatcher.FuzzySearch(searchName,x.Title));
return x.Score>0;
})

[jjw24]

score > 0 will return a lot of results that have a score, that's why we are using IsSearchPrecisionScoreMet(), it matches the precision level that the user selected, default is 50, so only results with a score equal or higher will return.

[taooceros]

Well, you are not right here. The score property will make every raw score lower than search precision become 0, so no worry for more results. The one you suggested that can be lower than search precision is called rawScore.

[jjw24]

yeah you are right about the score property.

I dont see a benefit of doing x.score > 0 as oppose to just calling the function which has the logic embedded without having to hardcode any numbers

[taooceros]

I mean by changing x.score to the score from the fuzzy search can make the result list sort since the view model will sort it by its score.

[jjw24]

can you give me a code snippet please, not sure what you mean

[taooceros]

I mean by setting the score of each Result can help the result list to sort it based on the score.
Check out this

Flow.Launcher/Flow.Launcher/ViewModel/ResultsViewModel.cs

Lines 156 to 201 in 920668d

	private List<ResultViewModel> NewResults(List<Result> newRawResults, string resultId)
	{
	var results = Results.ToList();
	var newResults = newRawResults.Select(r => new ResultViewModel(r, _settings)).ToList();
	var oldResults = results.Where(r => r.Result.PluginID == resultId).ToList();
	// Find the same results in A (old results) and B (new newResults)
	var sameResults = oldResults
	.Where(t1 => newResults.Any(x => x.Result.Equals(t1.Result)))
	.ToList();
	// remove result of relative complement of B in A
	foreach (var result in oldResults.Except(sameResults))
	{
	results.Remove(result);
	}
	// update result with B's score and index position
	foreach (var sameResult in sameResults)
	{
	int oldIndex = results.IndexOf(sameResult);
	int oldScore = results[oldIndex].Result.Score;
	var newResult = newResults[newResults.IndexOf(sameResult)];
	int newScore = newResult.Result.Score;
	if (newScore != oldScore)
	{
	var oldResult = results[oldIndex];
	oldResult.Result.Score = newScore;
	oldResult.Result.OriginQuery = newResult.Result.OriginQuery;
	results.RemoveAt(oldIndex);
	int newIndex = InsertIndexOf(newScore, results);
	results.Insert(newIndex, oldResult);
	}
	}
	// insert result in relative complement of A in B
	foreach (var result in newResults.Except(sameResults))
	{
	int newIndex = InsertIndexOf(result.Result.Score, results);
	results.Insert(newIndex, result);
	}
	return results;
	}

Although I don't believe this part of codes are clear enough, but it do provides the ability to sorts the results to display on the results list view based on their score.

[jjw24]

Ohh gotcha, I forgot to set the score for each of the result.

[jjw24]

sorted. good catch, thank you

[taooceros]

Well I do think it will be more elegent to simply use the Select method to get the resultlist but this is fine, too.

[taooceros]

addjust
is this typo hhh?

[taooceros]

Since we have referenced to Flow.Launcher.Infruastructure, why not simply use the one lies in Http.cs?

[taooceros]

Let's go!
