Fixes Issues in "Smart Search" [#5204]

This fixes the second of the issues I exposed in #5204

The problem was with the use of PHP strip_tags()

Using it a string of the kind &lt;h1&gt;Title&lt;/h1&gt;&lt;p&gt;This is the paragraph&lt;/p&gt; is translated to:
TitleThis is the paragraph

Adding a space after each &gt; does the trick...
