If the csv file isn't changing, load in it into a database, where searching is fast and easy. If you're not familiar with SQL, you'll need to brush up on that though.

Here is a rough example of inserting from a csv into a sqlite table. Example csv is ';' delimited, and has 2 columns.

import csv
import sqlite3

con = sqlite3.Connection('newdb.sqlite')
cur = con.cursor()
cur.execute('CREATE TABLE "stuff" ("one" varchar(12), "two" varchar(12));')

f = open('stuff.csv')
csv_reader = csv.reader(f, delimiter=';')

cur.executemany('INSERT INTO stuff VALUES (?, ?)', csv_reader)
cur.close()
con.commit()
con.close()
f.close()
