In California, where I have practiced law for 28 years, a title search is done by professionals at a title insurance company. At the close of escrow, it issues title insurance to the buyer and its lender. If it searched poorly, and you are damaged, you may make a claim against the title insurance company through your insurance. Generally, lawyers do no searches. Of course, title insurance, like all insurance, has a cost. But I have never heard a buyer object to the cost given the great benefit.
