Enhancement to search function?

1) Can i suggest to enhance the search function?
Currently, it only searches for key words in the topic.
It does not search in the posting itself.

I believe this will be good for newcomers to the forum, where they want to search for information, rather then creating a new topic.

2) can we also sort the marketplace based on coloumn headers?
Like, click on last date posted, to sort the latest posting.
Right now, it is fixed at topic creation date.
