I doubt you're thinking in terms of tokens. Your inputstream is broken up into tokens (think of them as words, depending upon the analyzer) and regex searchers are confined to those *tokens*. So the concept of a multi-line regex in a search is kind of ...odd...
You could possibly index your input as UN_TOKENIZED, but I really have no clue what Lucene would do with that. I think you're off in uncharted territory here. Perhaps a better thing would be for you to explain *why* you want to do this and perhaps folks can come up with some suggestions, I suspect this may be an XY problem, see http://www.perlmonks.org/index.pl?node_id=542341 Best Erick On Sun, Jul 26, 2009 at 9:52 AM, ba3 <sbadhrin...@gmail.com> wrote: > > I was trying to do a regex search with the lucene and > JavaUtilRegexCapabilities. > The code used is : > RegexQuery query = new RegexQuery(new > Term("contents","(?m)hello.*(\r[^#]*)This is to be searched.*(\r[^#]*)#")); > query.setRegexImplementation(new JavaUtilRegexCapabilities()); > > I verified the regex in : http://www.gskinner.com/RegExr/ [with the multi > line checked] > In lucene though there are no hits.
