Advanced Search

Advanced Search enables you to form and combine search sets. For example:

Set #3 consists of records in which cell death or apoptosis appears in the Title and Japan or Russia appears in the Addresses field.

An advanced search usually begins with at least two queries consisting of search terms prefaced by field tags.

The Search History table at the bottom of the page displays all successful searches that you ran during the current session. Search sets are listed in the Search History table in reverse numerical order - the most recently created set is at the top of the table.

Delete Sets

From the Search History or Advanced Search page:

• Select the check box in the Delete Sets column of the unwanted search query, and then click Delete to remove the search history set from the Search History table.

Or

• Click the Select All button to select all search queries, and then click Delete to remove all of the search historys set from the Search History table.

Dependent Sets: After you click Delete, the product checks for dependent sets. Selected sets that are not referenced in other sets are deleted. If, however, a set is referenced in a set that is not selected for deletion, the product returns the following error message.

At least one of the sets you have selected to delete is referenced in a set combination. We have marked the affected set combinations for you. Please verify the checkmarks and click DELETE to remove the sets.

In this instance, the product marks the Delete Sets check box of both the original set marked for deletion and the referenced set. You can either delete both sets or neither set.

Example 1: You create a set combination (set #3) that includes sets #1 and #2. You cannot delete set #1 because set #3 (the referenced set) is dependent on set #1. You can, however, delete both sets #1 and #3.

Example 2: You create a set (set #2) by using the Refine Results option from the Results page. You cannot delete this set because it is dependent upon the original parent set (set #1). You can, however, delete both sets.
