Using English with Equation trained data tesseract tess4j

Question

I'm trying to read an image with mathematical equations using tess4j in java. However, I think its overlapping the characters and not able to combine English with Equations. Is this a trained data issue? How can I fix this. Below is my code .

 ITesseract tess = new Tesseract();
        try {
            tess.setLanguage("eng+equ");
            String imageURL = "http://www.blah.com/images/test-exercises/exercises.png";
            URL url = new URL(imageURL);
            BufferedImage img = ImageIO.read(url);
            String result = tess.doOCR(img);
            System.out.println(result);
        } catch (TesseractException e) {
            e.printStackTrace();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

Output that I get
