Let's see... this is what the file has now:

    <message numerus="yes">
        <location filename="../../MainUI/FindReplace.cpp" line="131"/>
        <source>%1 match(es) were found.</source>
        <translation type="unfinished"><numerusform></numerusform><numerusform></numerusform></translation>
    </message>
    <message numerus="yes">
        <location filename="../../MainUI/FindReplace.cpp" line="177"/>
        <source>The search term was replaced %1 time(s).</source>
        <translation type="unfinished"><numerusform></numerusform><numerusform></numerusform></translation>
    </message>

I believe you have to fill in the <numerusform></numerusform> tags (I'd remove the type="unfinished" too), in English it would be:

    <message numerus="yes">
        <location filename="../../MainUI/FindReplace.cpp" line="131"/>
        <source>%1 match(es) were found.</source>
        <translation><numerusform>%1 match was found.</numerusform><numerusform>%1 matches were found.</numerusform></translation>
    </message>
    <message numerus="yes">
        <location filename="../../MainUI/FindReplace.cpp" line="177"/>
        <source>The search term was replaced %1 time(s).</source>
        <translation><numerusform>The search term was replaced once.</numerusform>The search term was replaced %1 times.<numerusform></numerusform></translation>
