NinjaNye.SearchExtensions.Soundex supports converting and searching for words that sound like a given word.

SearchExtensions.Soundex is a library of IQueryable and IEnumerable extension methods to perform 'sound like' searches. More information on these packages and it's use can be found by, visiting my blog.

Returning records that 'sound like' "test" using the Soundex algorythm:

Search where a single property sounds like a single search term

var result = data.SoundexOf(x => x.Property1).Matching("test")

Search where a any of multiple properties sounds like a single search term

var result = data.SoundexOf(x => x.Property1, x => x.PropertyTwo)
                 .Matching("test")

Search where a single property sounds like any one of multiple search terms

var result = data.SoundexOf(x => x.Property1).Matching("test", "another")

Search where a any of multiple properties sounds like any of multiple search terms

var result = data.SoundexOf(x => x.Property1, x => x.PropertyTwo)
                 .Matching("test", "another")

All the above soundex examples can be performed using the Reverse Soundex algorithm. Simply substitute in the ReverseSoundexOf() method. For example:

Search where a single property sounds like a single search term

var result = data.ReverseSoundexOf(x => x.Property1).Matching("test")

Search where a any of multiple properties sounds like a single search term

var result = data.ReverseSoundexOf(x => x.Property1, x => x.PropertyTwo)
                 .Matching("test")

The above SoundexOf and ReverseSoundexOf methods can also be applied to IQueryable data. For IQueryable we reduce the amount of records returned from the data source as much as possible but be aware that the soundex searching is performed on the in memory collection.
