Examine multiple fields search

Questions
1

Hi everyone.

Does anybody knows how to search multiple fields with Examine?
This is my code for one field , but it would be great if I could search the title as well.

var results = searcher.CreateQuery("content").NodeTypeAlias("topic").And().Field("topicBody", searchTerm).Execute();

Thank you
