Hi all,

My use case is that I have to calculate the LIX readability index for my
documents.

*LIX =3D A/B + (C x 100)/A*, where

*A* =3D Number of words
*B* =3D Number of periods (defined by period, colon or capital first letter=
)
*C* =3D Number of long words (More than 6 letters)

A can easily be done if the index size does not matter as I define a filed
in the schema without stemming and stop word elimination and use the term
vector compnent. I can calculate all the words, I can calculate easily the
number of long words also.
The only missin component is B.

Does anybody have idea how to get the number of "periods"?

Cheers
