Infact it was a single line change. Here is the patch. The change is
in dict/permute.cpp

For non-eng script the if condition was never getting satisfied and
hence the DAWG files were not being scanned properly. Adding a
any_alpha=1 on the top explicitly on the top solves this problem for
the time. There is probably a more elegant solution though.
By the way, I do not see this particular if condition in the trunk
anywhere in the file. Perhaps the deveopers have fixed it in the trunk
already.

Yes. The latest tesseract-indic download supports dictionary lookup.
