Search History: Use when your search is complex. As you search for articles, you will find keywords you didn't think of at the beginning. For example, in the search below, the searcher began with deforest* but later added two synonyms - clearcut* and slash and burn. These three keywords can quickly be combined into one result set by clicking the boxes for searches #1, #2, and #3 (in red) and selecting the OR circle (also in red). The results are displayed in #7. Then the various geographical locations are combined (in green) - costa rica, honduras, and latin america. Finally, those two sets (#7 and #8) are combined using AND (Blue)
You can save a search you performed so that you can repeat it in the future. This is useful if you have a rather complex search statement and will likely repeat it again later. You can also have the system run your saved search periodically and send new citations (those enter into the database since you last performed the search) to your email box.
You will need to establish a free account with Web of Knowledge before completing the setup.
