Add the ability to group fields when searching

[Timu57]

When using the "prioritize" algorithm the order of the fields is important.
The user should be able to group fields together.

[ "title", [ "subtitle", "content" ], "description" ]

In the example above "title" will have the highest weight. "subtitle" and "content" will have the same and second highest weight. "description" will have the lowest weight.

Would be nice to hear you opinions on that.

I just love the idea, and I see that SleekDB is moving fast to have great features and functionalities, such as MySQL why not :)
