[rules-users] Update vs insert

Hello, What is the difference between calling insert and update in a rule file? When I use insert my queries don't work, but if I use update they seem to. I don't mind using update, but I would like to understand the difference between the two. Here is my rule file. rule "Add person to math class" no-loop when person : Person(likesMath == true) then person.setClassName("Math"); insert(person); end I also have a query: query getPeopleForClass(String _className) Person(className == _className) end When I add two facts to working memory, where the likesMath attribute is true, then run my query I get zero results back. When I change the rule, "Add person to math class", to use update(person) instead of insert(person) two students are returned. Any help would be appreciated.
