This function is always used in combination (AND) with one of the search criteria offered by the assistant. It is only available for the FamPat and Fullpat collections.
You can restrict your search to publications included in the collection:
• In the last update, by selecting the option Most Recent Publication
• In the last two updates, by selecting the option Last Two Weeks of Publication
• In the last four updates, by selecting the option Last Four Weeks of Publication
Whenever you run the same search on a regular basis, you can find only new documents.
After using a limit to a database update, the number of previous search results is cleared from your search history. Your search will need to be run again.
