I looked for a form that the finders acceded by all the Web so that the products, commentaries, supplies,
new features, etc, appeared in these finders, since by defect many finders do not index in their data base those urls to which parameters do not go to him as it can be:
Asi that investigating that way averigué that exists a module of Apache with which you can modify urls to your taste, doing possible that the previous URL becomes for example:
default-50_39 3a 1 buy_now-47.html
This causes that the finders think that is a normal and current page HTML, causing that it indexes it in his data base.
