I want to do a search for Music instruments which has its informations Name, Category and Origin as I asked in my post.
But now I want to sort/group the result by similarity/equality to the keyword such as.
If I have the list
{ Harp, Piano, Drum, Guitar, Guitarrón }
and if I queried "p" the result should be { Piano, Harp }
but it shows Harp first because of the list's sequence
and if I add {Grand Piano} to the list and query "piano"
the result shoud be like { Piano, Grand Piano }
here's my code
static IEnumerable<MInstrument> InstrumentsSearch(IEnumerable<MInstrument> InstrumentsList, string query, MInstrument.Category[] SelectedCategories, MInstrument.Origin[] SelectedOrigins)
{
var result = InstrumentsList
.Where(item => SelectedCategories.Contains(item.category))
.Where(item => SelectedOrigins.Contains(item.origin))
.Where(item =>
{
if (
(" " + item.Name.ToLower()).Contains(" " + query.ToLower())
|| item.Name.IndexOf(query) != -1
)
{
return true;
}
return false;
}
)
.Take(30);
return result.ToList<MInstrument>();
}
Or the result may be like my old self-invented algorithm that I called "by order of occurence",
that is just OK to me.
Is there any way to do that, please tell me.
Thanks in advance.
