Mark Miller's Qsol Parser can do that [1]. However it seems that
temporarily it is not publicly available [2] [3].

The basic idea is to insert artificial tokens between sentences and
paragraphs at index time analysis. And use SpanNotQuery at search
time.
Another perhaps more tractable approach is to have a token filter that
bumps the position increment gap high when a sentence boundary is
detected. Then plain phrase queries will only match within a sentence
(unless the slop factor extends beyond the gap distance).
