The search capability is lacking. The 20 word maximum return makes it useless more times than not. I would suggest a couple of enhancements to make this a better tool:
1) A checkbox to indicate the entered letters must be at the beginning of all words returned.
2) A checkbox to indicate the entered letters must be at the end of all words returned.
3) A next button to display the next 20 words, or 50, or 100.
4) Wildcard searches using * and ? to indicate replacement of multiple letters or a single letter respectively.
Thanks for your consideration.
