            int startingIndex = fulltext.indexOf(boldText);
            int endingIndex = startingIndex + boldText.length();
         
            if(startingIndex < 0 || endingIndex <0){
                return builder.append(fulltext);
            }
            elseif(startingIndex >= 0 && endingIndex >=0){
                builder.append(fulltext);
                builder.setSpan(new StyleSpan(Typeface.BOLD), startingIndex, endingIndex, 0);
            }
        }else{
