Relevance is the default sort order. Other sort orders include Date: newest first, Date: oldest first, Citations: highest first, and more.
Use the 'Refine Results' feature to refine/filter your results. The first option is to search within the results. Some of the main filters include Publication Years, Document Types, Web of Science Categories (broad fields of study), Authors, and Publication Titles (e.g., Journal of Business Ethics).
Web of Science provides multiple options for getting full text:
For every result (unless it's very recently published) a clickable citation count is displayed, telling you how often the result is cited by other publications indexed in Web of Science. Click on such a link and a screen will appear with results (mostly articles) citing the result in question.
If you want to start a new search or add additional criteria to your current search, click the search box near the top of the screen, which gives you options to reset all search fields.
