Highlight words

Question

I need to highlight some words (search results) in TLF text editor. I am using RichEditableText.
Please tell me how I can highlight more than one word at different places (in several paragraphs or spans).
I tried to use selectRange() function in RichEditableText. but it highlights only one occurence.
Thanks.

Hi,
The same kind of stuff I have performed in my application . I am fully agreed with Robin's point but to be more explanatory you can do the following :
1. Find the begin and end of the text to be highligted. You can do it by using selection manager of text flow by the properties absoluteStart and absoluteEnd of selection manager
   like 
     var _selMgr:ISelectionManager = textFlow.interactionManager;
if(_selMgr.hasSelection())
                if(_selMgr.focused)
                    var begin:Number = _selMgr.absoluteStart;
                    var end:Number = _selMgr.absoluteEnd;
2. Once you get the begin and end you can get the start and end index of TextLine of the text flow like
   var startTextFlowLineIndex:int = textFlow.flowComposer.findLineIndexAtPosition(begin);
                    var endTextFlowLineIndex:int = textFlow.flowComposer.findLineIndexAtPosition(end);
and then get textline as
var textFlowLine:TextFlowLine;
textFlowLine = textFlow.flowComposer.getLineAt(startTextFlowLineIndex);
from text flow line you can get text line using
   textFlowLine.getTextLine()
methode
3. Get the bound of the first and last atom of the text lIne to draw a rectangle as
          var startbounds:Rectangle = textLine.getAtomBounds(textLine.getAtomIndexAtCharIndex(begin));
                var endbounds:Rectangle = textLine.getAtomBounds(textLine.getAtomIndexAtCharIndex(end));
Next very easy you can use sprite's graphic and drwa the rectangle.
