SimplifiedSearch

Simple way to add ranked fuzzy matching search.
For when you have up to a few thousand products, locations or similar and want to add a search that most users will see as smart, with minimal work.

Intended use case

Searching through lists of short phrases like country names or the subject line in emails.

.NET support

Tested with: NETCOREAPP3.1, NET5.0, NET6.0

Quickstart

Install

PM> Install-Package SimplifiedSearch

Code

Use extension method .SimplifiedSearchAsync(searchTerm, propertyToSearchLambda).
propertyToSearchLambda is optional. When missing, all properties will be searched (or the value, if the value is string, Enum, int, etc).

using SimplifiedSearch;

IList<Country> countries = GetListOfCountries();
IList<Country> matches = await countries.SimplifiedSearchAsync("thaiwan", x => x.CountryName);
foreach (var country in matches)
{
    Console.WriteLine(country.CountryName);
}
// output:
// Taiwan
// Thailand
