In addition to what robot_tourist has already advised, you could have a read at Designing a Search Engine, which raises a couple of things you may want to think about. You seem to have an idea about how you want this to work. With this in mind read Re^2: WWW::Mechanize problem, here someone has a list of URLs they wish to visit/parse. Limbic~Region provides a detailed description of the how to deal with these situations, which may be of interest to you also.

Update: used Super Search and added a link to a previous question related to this topic.

Hope this helps

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
