The problem is caused by this template:

> <xsl:template match="text()" mode="search">
>     <xsl:param name="term" select="''"/>
>     <xsl:param name="element" select="''"/>
>         <xsl:choose>
>             <xsl:when test="contains(.,$term)">
>                 <xsl:for-each select="ancestor::p[not(parent::note)][1]">
>                     <xsl:apply-templates/>
>                     <hr/><br/>
>                 </xsl:for-each>
>             </xsl:when>
>             <xsl:otherwise/>
>         </xsl:choose>
> </xsl:template>

It makes a textual copy of its container for each and every text node that  
contains the searched text.
You could add an expression to the 'xsl:when' that is only true at the  
first match:

<xsl:template match="text()" mode="search">
   <xsl:param name="term" select="''"/>
   <xsl:param name="element" select="''"/>
       <xsl:choose>
           <xsl:when test="contains(.,$term) and  
generate-id()=generate-id(ancestor::p[not(parent::note)][1]//text()[contains(.,$term)])">
                   <xsl:apply-templates  
select="ancestor::p[not(parent::note)][1]"/>
                   <hr/><br/>
           </xsl:when>
           <xsl:otherwise/>
       </xsl:choose>
</xsl:template>


You might also avoid the duplication by copying at the top rather than  
after diving in the tree. e.g.:

<xsl:template match="/">
<div>
	<xsl:for-each  
select="/*/*[local-name()=document('')/*/xsl:variable[@name='select-elements']/item][contains(.,$target1)]">
		<xsl:copy-of select="."/>
		<hr/>
	</xsl:for-each>
</div>
</xsl:template>
