Solr index vs stored

Question

I am a little confused as to what the behaviour of the index and stored attibutes of the Solr fields is.

For example if I have the following in the Schema.xml

Answer 1

If both are false you loose your data in that field. If indexed true, the data are searchable but it can not be displayed. If you set stored true you will not be able to search on that field but it can be displayed (in this case you can write copyfield rule to copy the info from that field to the default searchable field). Both set as true -> you can search and display.
