Glimpse/Webglimpse is a good search engine too.

Some tips if you want to develop it for yourself:

    You have to weigh the words by their source. The following is an example preference: Words from title: 100, words from meta keywords: 75, words from headlines: 50, words from the document body: 10.

    Store the place of the word in the given document. E.g. the word is in the first 100 words. When the user is looking for two or more words, you can compare the hits, as if the found words are closer to each other as the other findings. Then you can compute a rank.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":


  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
