How do I use the refine search feature?

The Refine Search feature works similar to a google search, except we are only searching articles in our database of answers. This tool is especially useful to broaden searches for plants. For example a more restrictive search, such as CRIMSON FOUNTAINGRASS produces no results, but by refining the search and removing the word CRIMSON produces several answers under the name PURPLE FOUNTAINGRASS. 

Another great use of the Refine Search feature is to add a keyword to get more information about diseases or problems that can attack your plant. Simple add the word PROBLEM or DISEASE or PEST to your search.
