There seems to be a bit of problem with searching for entries. When you input a term such as "cake" when you're looking for the "This cake is delicious you must eat it" entry you will get a lot of results. However some of these results are not cake related in any way and the article you're looking for isn't there. Only when you search for the entire phrase, with proper capitalization, you find what you were looking for in the first place.
Perhaps the search function can be broadened/narrowed in order to retrieve more accurate results. Also the results should be ordered by the ones with the search term in the title/tags first and the ones with the search term in the description second.
