Parameters

indexExpression
Expression<Func<TDependentEntity,Object>>

A lambda expression representing the property(s) to be included in the index (blog => blog.Url).

If the index is made up of multiple properties then specify an anonymous type including the properties (post => new { post.Title, post.BlogId }).

Returns
