Use the search bar to search for any word that may appear in a post. Additionally, posts are labeled using subject categories. You may select a category above to search for posts that have such a label. To search for multiple categories use the search bar and use the label: operator before listing each category of interest. For example, to search for all posts that have both the labels Report and SEM, enter the following label:report label:SEM. Be sure to use all lower case letters unless you are searching for an acronym.
