ADD

The ADD command is designed to increase your flexibility in searching across files. To use the ADD command, BEGIN in one or more databases that contain similar fields and search terms. At any point in your search, you can ADD one or more files, up to the maximum number of files allowed in a OneSearch. The new files are brought into your search without erasing the search results and strategy you've created in your original files.

You can then simply REPEAT the search in the new files, which will regenerate your previous sets so that they include the new files, or you can customize it to fit the structure and vocabulary of the new files.

In the following example, a search is begun in MEDLINE^®, File 154. Gale Group Health & Wellness Database^SM, File 149, is then ADDed, and the search is continued with a modified strategy to fit the search terms in File 149. The resulting sets from each file (S2 and S4) are ORed together, and REMOVE DUPLICATES is used to eliminate any duplicate records from the final set.
