I've been trying to use MultiFieldParser to search across multiple fields
using AND as the default grouping operator.
If I use
analyzer = StandardAnalyzer()
qp = MultiFieldQueryParser("field1", analyzer)
qp.setOperator(QueryParser.DEFAULT_OPERATOR_AND)
query = qp.parseQuery(q)
hits = searcher.search(query)
then it works to search the one field, but if I use
analyzer = StandardAnalyzer()
qp = MultiFieldQueryParser(["field1", "field2"], analyzer)
qp.setOperator(QueryParser.DEFAULT_OPERATOR_AND)
query = qp.parseQuery(q)
hits = searcher.search(query)
then it fails, just saying "Aborted".
It seems like the constructor for MultiFieldQueryParser will only take a
string as the first argument, not an array - is there a way round this?
Support for the MultiFieldQueryParser(String[], Analyzer) is missing.
The fix is simple enough and included in the patch to PyLucene.i below.
Let me know if this solves the problem for you.
Andi..
