is this normal ?
Yes, yes it is. If I had thought it was not normal, I would have said so.
What happens on the first press, is that it is submitted as a form - so the parameters are sent the way forms are sent, but page 2 and so on aren't forms, thus all the search parameters (not least, which boards to search in) have to be converted into a form that can be inserted in a link.
For large sites, this can be a lot of parameters and was observed that it could be too long for certain browsers to process (yes, there are some limits on the size of a URL), so the parameters are bundled together, compressed and turned into that string you see.
