Is your issue that you want the paragraphs to be in a single document, but you want to limit proximity search to find matches only within a single paragraph? If so, you could parse your document into paragraphs and when generating tokens for it place large gaps at the paragraph boundaries. Each Token in lucene has a startOffset and endOffset that you can set as you generate Tokens inside TokenStream.next() for the TokenStream returned by your Analyzer. Those classes and methods are all in org.apache.lucene.analysis. Or alternatively, you could make each paragraph a separate field value and use Analyzer.getPositionIncrementGap() to achieve essentially the same thing (except that your Documents could get unwieldy if you that have many paragraphs). If this is not what you are trying to do, then please explain your objectives precisely.
