plz help me to decide best metric

  • My database is very huge consisting of name ,address, date of birth. I want to know which is the best suitable metric for this task, so that it is capable of removing false positives. for eg:

    1st stage california
    1st stage bingio.

    if i give 1st stage bingio in search criteria it should not retrieve me the  1st stage california..

    similar the case with date of birth etc...

    Iam looking for a hybrid method for a better precision. Please help me to find which is the best combination for the search of name, address and Date of birth..simultaneosly without required to use different metrics independently.

    thank u
