The way that OneSearch was set up by EBSCO, its publisher, duplicates aren't removed until you reach the last page of your search results. So to see the total number of unique results for your search, simply page through your results until you get to the last page of results. When you get to that page, the duplicate records will automatically be removed and you'll see the number of unique results for your search, as noted at

Note that duplicates won't be permanently removed when you reach the last page of your search results, though; if you return to earlier pages of your result set, your results will include duplicates again.

To see a de-duped set of search results, you can export your search results from OneSearch, as the downloaded results will not include duplicates. Instructions for exporting your results can be found at Exporting search results.

ProQuest databases (ABI/INFORM Collection, Dissertations and Theses Global, Healthcare Administration Database, News & Newspapers)

To remove duplicates from any ProQuest database, scroll down on the advanced search page and click on the Result page options link and then check the box next to Exclude duplicate documents.

Across multiple databases

To remove duplicates across multiple databases, you can export all of your search results into a bibliographic management system such as Mendeley, Zotero, Endnote, RefWorks, etc. and then use that system's de-duping feature to remove duplicates from your result set.

Important note: Some duplicates may still remain in your result set regardless of which system you use for de-duping, so you may need to manually review results in order to ensure that your results contain no duplicates.
