How do I apply specific date limits to Ovid search results?
In Ovid databases, it is possible to narrow search results by whole years using the Publication Year filter under Limits:
Some Ovid databases also facilitate searching within parts of years - see guidance below.

After running a MEDLINE ALL search, type and search for the following, using Advanced Search:
limit X to dt=YYYYMMDD-YYYYMMDD
dt represents Creation Date, and X should be replaced with the number of the last line of the search before the date limit is to be applied. For example:
limit 4 to dt=20240101-20240615
Here is a MEDLINE ALL search with the above date range added:
1 Neoplasms/ or cancer*.mp. 2814930
2 Depressive Disorder/ or depression.mp. 583477
3 Aged/ or elderly.mp. 3792561
4 1 and 2 and 3 9328
5 limit 4 to dt=20240101-20240615 226
In this example, search results found by line 4 have been filtered so that only those added to the database between 1st January 2024 and 15th June 2024 are retrieved (line 5).

Filter Embase results by specific dates in a similar way to MEDLINE ALL, but change dt to dd (First Date):
limit X to dd=YYYYMMDD-YYYYMMDD
Example: limit 4 to dd=20240101-20240615
—
Use up (Update Code):
limit X to up=YYYYMMDD-YYYYMMDD
Example: limit 4 to up=20240101-20240615
