Are you looking for the location of a class, a method or a function in the PrestaShop codebase?

Type its name (without parenthesis) and click "Search" to display useful information: item type, version of PrestaShop, and file path.
The version of PrestaShop is very important: it tells you where the searched item can be found — which helps you know when it was deprecated.

For instance, cmpPriceAsc was a method from v1.0 to v1.1.0.1, and then a function from v1.2.0.1 to the current version.
