I'm sure there's some obvious explanation for this that I'm missing -- I can't get the SearchFiles demo class to work. I can successfully use the IndexFiles class to index a directory, but searching doesn't work; I just get a NullPointerException.
So I wrote my own Search class, which is basically just a slightly tweaked version of SearchFiles. And I get a NullPointerException there as well. I added a stack trace, which shows the exception coming from IndexSearcher.explain(). Any ideas? I've attached the source for Search.java, and below is the stack trace. thanks, Michael > $ java Search > Query: casino > Searching for: casino > caught a class java.lang.NullPointerException > with message: null > java.lang.NullPointerException > at org.apache.lucene.search.IndexSearcher.explain(IndexSearcher.java:196) > at org.apache.lucene.search.Hits.getMoreDocs(Hits.java:93) > at org.apache.lucene.search.Hits.<init>(Hits.java:80) > at org.apache.lucene.search.Searcher.search(Searcher.java:71) > at org.apache.lucene.search.Searcher.search(Searcher.java:65) > at Search.main(Search.java:35) > >
