Hello grai. Once you've searched for a particular term, you can then filter the results further, to prevent you from scrolling through all of the results pages. You can choose to view articles (i.e. projects, problem pages, blogs etc), forum posts or plant profiles. So, for example, if you search for 'Window boxes', then click the 'articles' button, you'll see a list of all the content types in the left-hand menu:
Search results for 'window boxes', filtered by article
Search results for 'window boxes', filtered by forum posts
We've deliberately included forum posts within the site-wide search, to allow people to find all the content related to any particular topic on gardenersworld.com. I hope this helps.
