What is a dynamic replacement and when does it work?

A dynamic replacement is used when EmEx 3 cannot recognize information though it is explicitly presented on the website. After thorough investigation it becomes obvious that this information is protected either to prevent automatic collection or be allowed through forum and blog filters and other website engines.

Most frequent examples are a replacement of the symbol @ by a picture, or the word http:// to _xxxx://

You should understand when automatic replacement works:

you can see on the diagram that automatic replacement will influence all parsers which will be active, but it won't affect keyword filter (it's used to enable work with the original source instead of the change one).

You should take this into consideration in order not to interfere into URL parser work.
