You can view the results of previous searches, incorporate them into new searches, or combine them into one result set:
- To see a list of the searches you have made during your current session, click on history from the menu bar.
- To review the results of a search, select it, and click view.
- To erase a search, select it and click delete.
- To combine/cross the actions of two or more previous searches, select them, and clickcombine.
Combine lets you work in various ways with more than one results set. For example, if you searched for Chicago, and now want to do a similar search for Illinois, you can combine them by choosing a predefined logical operation: AND, OR, first set NOT second, second set NOT first.
