So in short you have a static 5G dataset, that you need to search frequently.

I think your best bet would be use a database to index the data, and let it worry about how to create an optimised index.

I would put the entire file contents into the database, and discard the original file. If each line also contains lots of other stuff that you will not be searching on, then I would still keep it in the database, but I would put it in a different collum without an index so as not to bloat the database to much.


In reply to Re^3: search a large text file by chrestomanci
in thread search a large text file by perl_lover_always

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.
