basically you are not cathcing the case where there is a userID that has only ONE entry, and that one entry is a '-'..

Oops - good catch. Duplicating the if() with the regex is probably the right way to go here.

I'm thinking that the way to go may to be have 2 different scripts. one that just deletes the rows with '-' in the query field. then after running it I run the one that my prof wrote to cluster it.
heres a link to where I downloaded the datasets from originally. http://www.gregsadetsky.com/aol-data/ its a really interesting dataset just to open up and look at and see what people are searching for. |
Run 'perldoc warnings' and 'perldoc strict' for an in-depth explanation. Basically, together they warn you if you're doing 'unwise' things, like not initializing your variables with 'my', for instance. Experienced perl coders pretty much always use them. It just encourages better style, and fewer bugs.
I think match000's solution of testing for a '--' in the 'else' clause too is probably the best way to go there.
