Hi, I have the following test case point to the index generated in our
application. The result is confusing me and I don't know the reason.
Lucene version: 2.9.0
JDK 1.6.0_18
public class IndexTest1 {
public static void main(String[] args) {
try {
FSDirectory directory = FSDirectory.open(new
File("/path_to_index_files"));
IndexSearcher searcher = new IndexSearcher(directory, true);
PerFieldAnalyzerWrapper wrapper = new PerFieldAnalyzerWrapper(new
StandardAnalyzer());
wrapper.addAnalyzer("f1string_sif", new KeywordAnalyzer());
wrapper.addAnalyzer("f2string_ti", new
StandardAnalyzer(Version.LUCENE_CURRENT));
Query query = new QueryParser("f1string_sif", new
StandardAnalyzer(Version.LUCENE_CURRENT)).parse("f2string_ti:subbank*");
System.out.println("query = " + query);
System.out.println("hits = " + searcher.search(query,
100).totalHits);
searcher.close();
} catch (Exception e) {
System.out.println(e);
}
}
}
Output:
query = f2string_ti:subbank*
hits = 6
If I change the line to the following:
Query query = new QueryParser("f1string_sif", new
StandardAnalyzer(Version.LUCENE_CURRENT)).parse("f2string_ti:rdmap*");
Output:
query = f2string_ti:rdmap*
hits = 4
The above result are both correct based on my data.
Now if I change the line to:
Query query = new QueryParser("f1string_sif", new
StandardAnalyzer(Version.LUCENE_CURRENT)).parse("f2string_ti:subbank* OR
f2string_ti:rdmap*");
Output:
query = f2string_ti:subbank* f2string_ti:rdmap*
hits = 2
I assume the count in the last result should be larger than max(6,4), but it is
2. Any reason for that?
Thanks
