but in Java I can't work out how to phrase the code so that it
works properly. What I'm trying to do is:
String[] fields = {"field_a","field_b"}; Analyzer analyzer =
new StandardAnalyzer(stopwords);
QueryParser qp = new MultiFieldQueryParser(fields, analyzer);
qp.setOperator(QueryParser.DEFAULT_OPERATOR_AND);
Query query = qp.parse(q);
Hits hits = searcher.search(query);
The simplest way to debug this is to look at the sources for
MultiFieldQueryParser.java. The Java Lucene trunk version is here:
http://svn.apache.org/repos/asf/lucene/java/trunk/src/java/org/
apache/lucene/queryParser/MultiFieldQueryParser.java
If you need to look at an older release's version, PyLucene 1.9.1
was built from http://svn.apache.org/repos/asf/lucene/java/tags/
lucene_1_9_1
That's where I get confused, because it has
public MultiFieldQueryParser(String[] fields, Analyzer analyzer) {
super(null, analyzer);
this.fields = fields;
}
right at the start.
Never mind, I think java was picking up an old version of Lucene that
was installed in the system path.
Sorry for the inconvenience.
