Multi-sentence queries don't work properly when sentences are all lower case

[Manthan Dave]

Current logic relies on having an upper case letter followed by a whitespace after a period. So the following is fine:

Hello. How are you doing?

While this won't work:

hello. how are you doing?

Solution might involve capitalizing letters after spaces before splitting it but then it won't work with the following sentence:

Hello Mr. Anderson. How are you today?

That will detect three sentences like so:

Hello Mr.
Anderson.
How are you today?

Maybe certain words are excluded from sentence splitting and therefore are part of the same sentence?
