Combining Sets Using Search History
Searches in BA/BP may be complex searches that require two or more component searches to be combined.
You can either search within a particular search set (Refine Results / Search within results for... option, located below the Search for box) or do a New search:
Doing a new search is recommended because it allows more control over combining sets.
Search for the first component, and then search for the second component, and so on, until all component searches are completed. As each search is completed, it is added to the search history, which can be viewed by clicking on Search History. Here you can select which searches to combine with AND or OR:
Restricting Retrieval by Limiting Search Results
In the right-side menu of the results list screen, click on the desired limit
under Refine Results. The following limits are available on the limit page.
After selecting the desired limits, click on the Refine button beneath each option.
Field searching can be used to limit a search by document type (as letter or technical report) or literature type (as editorial, meeting report).
Information on Field searching is available through the Topic, Author, Title searches tab and the Biological Abstract Help Pages.
