Difference between 检索 and 找 I'm interested in what the exact difference is in usage between 检索 and 找 －  I know that we can saying 检索资料  but I'm wondering if we could "检索" something that is a bit more concrete.

For example, could I say “检索例句“ or would only 找 work in this context? 

Also, is  检索 too formal to use in spoken conversation?  

Thanks again for all of your help guys!
As @Stan said, 檢索 is usually used with database(資料庫) or library catalog(圖書目錄).

You must have some reference (a catalog, or a list...etc) to be able to 檢索. It's not only formal but more restricted. Whereas 找 can be used very widely.

For example one would say "在資料庫裡檢索資料", "在圖書目錄裡檢索資料", and "在網路上找資料", "在圖書館裡找資料", ...etc.

So you can search (or find) (找) for information  in any suitable places (or under certain conditions). But you would look up (檢索) for information only in restricted places like database.
