Metasearch engine parser:PHP

    I am trying to build a metasearch engine.

    First I need to make a query parser. The parser need to be able to recognise AND, OR, NOT operators and basic punctation. I intend to use PHP.

    a)Do i need a parser? Or is the the query input sent to the respective search engine API's to parse automatically when the user clicks enter?
    b) If so, where can i get information on how to build a PHP parser script for a metasearch engine? The project is due in one month. I suppose I'll have to dig into a php manual.
    c) Am I correct in saying that the parser script is located in the same page of code as the aggregation algorithm for the results from the 3 underlying search engines??

    Thanks in advance
