The above is incorrect, it will return 0 when evaluated against the
following xml document:

<t>
  <tu>
    <tuv>
      <seg>Y
        <ut>X</ut>Y
      </seg>
    </tuv>
  </tu>

  <tu>
    <tuv>
      <seg>Y
        <ut>X</ut>X
        <ut>X</ut>X
      </seg>
    </tuv>
  </tu>
</t>

when in fact the correct result is 1 (the second of the //seg elements
has two text node children containing 'X').

The right XPath expression is:

count(
//seg/text()
      [contains(., $SearchText)]
           [not(preceding-sibling::text()[contains(., $SearchText)])]
      )

As you can see, there is a combination of searching and grouping in
this XPath expression.
