Ian,
Thank you for getting back to me. No, I do not get a bogus hit from searching
the small index alone. Also, I do not get a hit if I delete any more documents
from the larger index.
I have updated my test to use RamDirectory and also print maxDoc() for the
searchables and the searcher, all numbers are as expected. I have posted all
the code, but did not want to post the indexes due to their size (2.2 meg
uncompressed). I will mail them to anyone who can help.
Here is the complete latest test code and its output
public class LuceneTest {
static public void main(String[] args) {
try {
QueryParser queryParser = new QueryParser(Version.LUCENE_30,
"author", new KeywordAnalyzer());
Query query = queryParser.parse("author:bentalcella AND NOT
publish_date:[20100601 TO 20100630]");
Searchable[] searchables = new Searchable[2];
RAMDirectory ram1 = new RAMDirectory(new NIOFSDirectory(new
File("/home/dfertig/testIndexes/b1")));
RAMDirectory ram2 = new RAMDirectory(new NIOFSDirectory(new
File("/home/dfertig/testIndexes/m1")));
searchables[0] = new IndexSearcher(ram1, true);
searchables[1] = new IndexSearcher(ram2, true);
MultiSearcher searcher = new MultiSearcher(searchables);
System.out.println("MaxDocs for index 1: " +
searchables[0].maxDoc());
System.out.println("MaxDocs for index 2: " +
searchables[1].maxDoc());
System.out.println("MaxDocs for MultiSearcher: " +
searcher.maxDoc());
System.out.println("Query: " + query.toString());
TopDocs topDocs = searcher.search(query, 10);
System.out.println("Results: " + topDocs.totalHits);
for (int in = 0; in < topDocs.totalHits; in++) {
Document document = searcher.doc(topDocs.scoreDocs[in].doc);
System.out.println("publish_date: " +
document.get("publish_date"));
}
searcher.close();
ram1.close();
ram2.close();
} catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
}
}
}
Output:
MaxDocs for index 1: 1
MaxDocs for index 2: 1000
MaxDocs for MultiSearcher: 1001
Query: +author:bentalcella -publish_date:[20100601 TO 20100630]
Results: 1
publish_date: 20100606

Subject: Re: Search returning documents matching a NOT range
Do you get the bogus hit on the small index if search that index
alone? Are you positive it only holds the one doc? Loading the one
doc into a new RAM based index in the test would prove it.
You are more likely to get help if post a self-contained example -
people can see everything relevant and are more likely to spot a
problem.
