By inserting keywords you may search for post text containing your terms and on right side , at the end of each description , you will find the author's name.
If the Forum grows this is an helpful tool as it would search in the whole forum-database what you are looking for.
Imagine there are 85 records , you should then be able to view them at 15 items per page [ as it is set ] , so you should surf and search in 5 pages to look for your result.
Test tip : insert the word "test" that is used at least in two posts.
