Finding something in windows is easier

Question

I don't understand why Apple can't release a new version of Spotlight that index all the files, for example if you want to search a word inside a PHP file you don't have any results, in Windows you can do this very easy, and I can't figure a way to do it on Mac os X.
I have found a way to index PHP files in Mac os X but it takes a lot of steps, and a lot of people would avoid doing this.
Is there a way to find text inside documents like windows? Why you need to index the contents of all documents to find something, in windows you don't need to do that, this way I can find files.
Here is how you can index PHP files in mac os x:
Here's how to get Spotlight to index your PHP scripts. In the Finder, navigate to /Library/Spotlight and locate SourceCode.mdiporter (this is installed with the Developer Tools). Select the file, control-click on it, and choose "Show Package Contents" from the pop-up menu. Now go into the Contents folder in the newly opened window. Double-click on info.plist (this should launch Property List Editor).
Click the triangle to expand Root, then expand CFBundleDocumentTypes, expand 0, then finally expand LSItemContentTypes. Click on the last number in the list (for me it was 6), then click the New Sibling button in the toolbar to add a new key. For the string value, enter public.php-script.
Close the Property List Editor and save when prompted. Go to a Terminal prompt and type:
mdimport -r /Library/Spotlight/SourceCode.mdimporter
Spotlight will now set to work indexing all your PHP files.
( WHERE I CAN DOWNLOAD SourceCode.mdiporter )
PLEASE APPLE FIX THIS PROBLEMS AND LET US SEARCH ALL THE DOCUMENTS LIKE WINDOWS, THIS WOULD BE VERY USEFUL.
ALSO MODIFY SPOTLIGHT TO INDEX ALL DOCUMENTS, WHAT IS THE DIFFERENCE IN A HTML DOCUMENT FROM A PHP FILE, OR PERL FILE, THE INSIDE OF THE TEXT IS THE SAME.

Ramiro -
Please be sure to tell Apple directly of your concerns:

That's the best way to let them know. And the more they hear from folks who are unhappy with Spotlight, the more likely it is they will do something about it. (Crosses fingers and hopes --)
