switchable option between default boolean 'AND' and 'OR' operators in search

Customer wishes to have an option or property in which the default behavior of JIRA's operator in the search bar can be changed from 'OR' to 'AND' so that you don't need to manually specify 'OR' each time in a search.

Customers comments (originally sourced from JSP-17318 and also JRA-5930).

You have to keep in mind that people are now used to using a "google like" ability and while the arguments made on issue JRA-5930 are okay I don't think they are solid enough to justify ignoring the issue.

Since confluence is using the AND by default, then why not be consistent. I believe that is what Atlasssian is now pushing with your new JIRA studio. The fact that it is a uniform platform. If you want your platform to be uniform then what could be more important than having a uniform way of searching for stuff regardless of which product I am using?

If you guys are really worried about affecting existing users that are used to the OR default, then give me a system parameter that I can set based on my preference. Then this would make everyone happy.
