Easily edit searches with Ovid Search Launcher
Note: the Ovid Search Launcher works inconsistently off campus via Open Athens for complex queries. It may be best to plan your use of this tool for when you are on campus, if possible.
Ovid Search Launcher allows you to enter your search in plain text, and run it in any UniSA-subscribed database on Ovid. The Launcher provides a quick and easy way to edit your searches while avoiding inconvenient timeouts on the Ovid platform. There is a character limit (with spaces) of approximately 5,950 (most searches are not this long!).
Paste a plain text version of your search strategy into the search launcher, select the database you want to search from the 'Choose databases' drop down menu, and then click outside the menu to retain your selection.
Off campus users: select the OpenAthens authentication checkbox, and enter 'University of South Australia' when prompted to Find your institution. Select the option with UniSA logo.
The codes below align with the UniSA subscriptions. It is recommended to search one database at a time.
- MEDLINE - medall
- Embase - emczd
- Emcare - emcr
- PsycInfo - psyh
- JBI - jbi
- Ovid Search History Launcher
The Ovid Search History Launcher allows you to build, edit, and run searches across UniSA-subscribed databases on Ovid.
