Dear Maghouin Beg,
It would be immensely handy if you could index things properly by use of 'labels'. Some words make excellent search terms.
In this particular case, when you know that you have posted your recipe for Chocolate Brownies, the 'excellent search terms' are 'baking' and 'recipes'. It makes life so much easier, well, the baking element of life, so much easier when you think to label a recipe for gluten-free Chocolate Brownies with the keywords 'recipes' and 'baking'. It doesn't take anywhere near as long to search for the recipe.
