Title: NIST: spectral lines not showed

Hello,

Thanks for providing a python based query to NIST. I think this will help me a lot.

I am facing a problem and I do not know if it is a bug with the code or with the user (in this case, myself). There are some spectral lines that the query to don show. For example, I did this query:

```python
In [55]: table = Nist.query(4000 * u.nm, 4200 * u.nm, linename="O II", wavelength_type='vac+air')

In [56]: print table
```
```

-- 4147.08 -- 33500.0 C 32.147622 - 32.446508 2s2.2p2.(1D).4s | 2D | 3/2 2s2.2p2.(3P).5p | 2D* | 3/2 -- T5723LS L7243
```

And I got just this two lines when NIST shows me a lot more. Why? Have I missed something?
