full-text search on in-memory business objects

I would like to ask for advice on best-practices concerning search on in-memory objects.

Our business data is represented as in memory C# objects. It is explicitly specified which properties of the objects should be matched. I supposed to be able to select those business objects that match to a search-phrase where the search-phrase may contain wildcards (no boolean operations). I have full开发者_C百科 control on the entire code.

How would you implement search in this case?
