In search of sb/sth：If you go in search of something or someone, you try to find them. （寻找、寻求）
E.G.1：That night, Samantha went on a date with a flesh and blood man…while the three of us went in search of furrier companionship.
E.G.2：While I watched my ex get a Mesopotamian lap dance…Susan Sharon made a play for Mr. Marvelous. I don’t know if I can deal with being single all over again. Every relationship has its ups and downs. My husband and I work very hard. We probably don’t spend enough damn time together. Compounded by the fact that neither of us gets enough sleep. Then again, who does? I really never imagined myself as a divorcee, you know? But I do think it’s more important to till your own soil than to go in search of greener pastures.
