If you dont have the test case, use C++ or any language to write one. Create a 32000 lines or more using loops, random ID from 0 to 4000000000 using
(unsigned int)((double)rand()/RAND_MAX * 4000000001)
then random a "string" length 5 for the title. For this one, random a single char 5 times using
(char)(rand()%26 + 97)
Write all those things in a text file.
Hope that helps
