Note that "XXX" is the value of the *first* text node within the <seg>
element, whereas "YYY" is the *last* text node within the <seg>
element. You're doing:

You're testing whether the <tu> element contains a <tuv> element that
contains a <seg> element whose *first* text node contains $SearchText.
Why is it only looking at the first text node? Because the first
argument to the contains() function is a string, and when you convert
a node set to a string, you get the first node in the node set.

I'm not sure what you're wanting to do. If you want to include the
text within the <ut> element in your search, you should use:

  <xsl:if test="tuv/seg[contains(., $SearchText)]">

If you're not interested in the text inside the <ut> element, then
look at the values of the text() nodes with:

  <xsl:if test="tuv/seg/text()[contains(., $SearchText)]">
