Syntax

IRavenQueryable<T> Search<T>(
      Expression<Func<T, object>> fieldSelector,
      string searchTerms,
      decimal boost = 1,
      SearchOptions options = SearchOptions.Guess,
      SearchOperator @operator = SearchOperator.Or)

Parameters
fieldSelector	Expression<Func<TResult>>	Expression marking a field in which terms should be looked for.

Return Value
IRavenQueryable	Instance implementing IRavenQueryable interface containing additional query methods and extensions.

List<User> users = session
  .Query<User, Users_ByNameAndHobbies>()
  .Search(x => x.Name, "Steve")
  .Search(x => x.Hobbies, "sport")
