Hi, by default there is no "_all" field. E.g., Elasticsearch adds this special field depending on your index mapping at the time of indexing the data. Internally this is indexing every field a second time into the "_all" field.
With Lucene you have to do this on yourself. An alternative would be to use another query parser (like the SimpleQueryParser, see http://goo.gl/4blGsp) that allows to expand the query to search on multiple fields with different weight factors.
