Wordpress - import CSV and then search


I would like to import a CSV file of names, addresses and phone numbers into Wordpress and then have a search function on a web page where a user searches for a name and all the details appear.

Please could someone let me know how to do this please ? I know there are plug in to import CSV files - but in outline - how do I search the database and portray the information ?

Many thanks for the help - much appreciated.
