If this file has a predefined construct, e.g.: title: someting location: new york .... then you can write a simple parser that extracts that information.
But I think otherwise this falls outside the scope of Lucene, unless I misunderstood you. If I had to give it a long shot though, I'd try to index all the data using WhitespaceAnalyzer, and then query for "Location". I'd also use the Highlighter in contrib to find matching segments of text, and take whatever has come after "Location". You should know though how much to take after Location ... Maybe if you post here a sample input, it'll trigger something in me :).
