In this thread: http://forums.adobe.com/message/2933158#2933158 you find some references to scripts that do exactly that. They're in JS but you should be able to see how to handle this. But if as you say you're very new to scripting, then this is probably too difficult.

Hi Try this code...

I created this for windows XP, Indesign CS4.

#targetengine "session";
var myDoc = app.activeDocument;
var stories = myDoc.stories.everyItem ().getElements ();
var myFind = new Array(); var myCounter = 0;
var times1, times2;
times1 = new Date().valueOf();
 
 
//-----------------------------For display---------------
var w = new Window ("palette", "Hyphenated words");
var list = w.add ("listbox", undefined, "", {numberOfColumns: 1, showHeaders: true,columnTitles: ["Hyphenated Word"], columnWidths: [185]});
    list.maximumSize.height = $.screens[0].bottom-200;
var myStory_id = new Array(); var myitem_id = new Array(); 
//------------------------------------------------    
main();
times2 = new Date().valueOf();
 var timeTaken = ((times2-times1)/1000);
displayWindow();
if (myCounter > 0){
w.show();
}
else { alert("Double Hypehnation Not Found"); }
 
function main(){
    var lineCount;
    myResetFindChangeGrep ();
    app.findGrepPreferences.findWhat = "(\\w+)([-~=])(\\w+)";
    var myIndex = new Array();
    for (i=0; i<stories.length; i++){
        myFind[i] = stories[i].findGrep(true);
        for (j=0; j<myFind[i].length; j++){
            lineCount = myFind[i][j].lines.length;
            if (lineCount>1){                
                var story_id = i; var myFind_id = j;
                var myText = myFind[i][j].contents;
                addItem(myFind[i][j], i, j);
                myCounter++;
                }//End if
            }//End of Find Length
        }//End Story length
    //alert(myIndex.length);
    }
 
//------------------------Function Declarations--------------
 
function displayWindow(){
    //window declared as global variable here 
    var panel1 = w.add('panel');
    panel1.minimumSize.width = 210;
    var group1 = panel1.add('group');
        group1.orientation ='row';
    var close_ = group1.add ("button", undefined, "Close", {name: "ok"});
    group1.add("statictext", undefined, "Fetched in "+timeTaken+" sec");
        close_.maximumSize.width = 44;
    list.onDoubleClick = function ()
        { 
            if (this.selection != null ) {
            var myIndex = this.selection.index;
            var storyNum = myStory_id[myIndex];
            var findNum = myitem_id[myIndex];
            var selectText = myFind[storyNum][findNum];
            app.select (selectText, SelectionOptions.replaceWith);
            app.activeWindow.zoomPercentage = 200;
            }
        } 
    
    close_.onClick = function () {w.close ()}
    }
function addItem(myItem, sto_id, item_id){
    list.add ("item", myItem.contents);
    myStory_id .push(sto_id);
    myitem_id .push(item_id);
    }
function myResetFindChangeGrep(){
    app.findGrepPreferences = NothingEnum.nothing;
    app.changeGrepPreferences = NothingEnum.nothing;
    app.findTextPreferences = NothingEnum.nothing;
    app.changeTextPreferences = NothingEnum.nothing;
}
