Search by opportunity

Hi, I’m not able to search by opportunity from the top drop down because when I select “opportunity” and enter opportunity name into the search box, the search resets to contact search.
Is there a fix for this? Thanks.

That search is for contacts with the search criteria having an opportunity record. Essentially it’s saying, show me a list of all opportunities associated with anyone having the last name ‘smith’ or the first name ‘tom’ or what not…
