Soundex Searching

Soundex search allows you to search any number of string properties returning those that 'sounds like' any of the given search terms. Soundex searches can be made against any number of search terms.

Methods

The following methods are available to both IQueryable data and IEnumerable data.

• Soundex - target property contains any of the search terms provided.
• ReverseSoundex - target property contains all of the search terms provided.

As of Release 1.1, NinjaNye.SearchExtensions supports converting and searching for words that sound like a given word.

Performing Soundex searches

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

Search where a single property sounds like a single search term

var result = data.Search(x => x.Property1).Soundex("test")

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

var result = data.Search(x => x.Property1, x => x.PropertyTwo)
         .Soundex("test")

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

var result = data.Search(x => x.Property1)
         .Soundex("test", "another")

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

var result = data.Search(x => x.Property1, x => x.PropertyTwo)
         .Soundex("test", "another")

Performing ReverseSoundex searches

The reverse soundex algorithm is calculated in the same way as the soundex code, the difference being that the word is reversed before the code is calculated.

Search where a single property sounds like a single search term based on the reverse soundex algorythm.

var result = data.Search(x => x.Property1).ReverseSoundex("test")

Search where a any of multiple properties sounds like a single search term based on the reverse soundex algorythm.

var result = data.Search(x => x.Property1, x => x.PropertyTwo)
                 .ReverseSoundex("test")

Search where a single property sounds like any one of multiple search terms based on the reverse soundex algorythm.

var result = data.Search(x => x.Property1)
                 .ReverseSoundex("test", "another")

Search where a any of multiple properties sounds like any of multiple search terms based on the reverse soundex algorythm.

var result = data.Search(x => x.Property1, x => x.PropertyTwo)
                 .ReverseSoundex("test", "another")

The above methods can 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.
