Line Break

Get 0 search results if there is a line break within the quellcode of a blog post in the DB. How can I get this solved?

If I coppy the search string directly from the DB which contatins the area of two tags <tag1> and <tag2> they are coppied as <tag1><tag2> when I insered them in the search field… but in the DB they are shown this way:

<tag1>
<tag2>
