---------------------------------------------
Hi [~ehaubert], thanks for the reply.
I think the current patch could be completed adding a test that verifies the
actual query (building) parsing.
The bug affects the query (building) parsing in the end, so, testing on results
per query can be effective, but it's not testing the bugfix.
Adding something like this should work :
public void
testEdismaxQueryParsing_multiTermWithPf_shouldParseCorrectPhraseQueries()
throws Exception {
Query q = QParser.getParser("foo a b bar","edismax",true, req(params("sow",
"false","qf", "text^10","pf", "text^10","pf2", "text^5","pf3",
"text^8"))).getQuery();
assertEquals("+(" +
"((text:foo)^10.0) ((text:a)^10.0) ((text:b)^10.0) (((+text:tropical
+text:cyclone) text:bar)^10.0)) " +
"((spanNear([text:foo, text:a, text:b, spanOr([spanNear([text:tropical,
text:cyclone], 0, true), text:bar])], 0, true))^10.0) " +
"(((text:\"foo a\")^5.0) ((text:\"a b\")^5.0) ((spanNear([text:b,
spanOr([spanNear([text:tropical, text:cyclone], 0, true), text:bar])], 0,
true))^5.0)) " +
"(((text:\"foo a b\")^8.0) ((spanNear([text:a, text:b,
spanOr([spanNear([text:tropical, text:cyclone], 0, true), text:bar])], 0,
true))^8.0))", q.toString());
q = QParser.getParser("foo a b tropical cyclone","edismax",true,
req(params("qf", "text^10","pf", "text^10","pf2", "text^5","pf3",
"text^8"))).getQuery();
assertEquals("+(" +
"((text:foo)^10.0) ((text:a)^10.0) ((text:b)^10.0) ((text:bar (+text:tropical
+text:cyclone))^10.0)) " +
"((spanNear([text:foo, text:a, text:b, spanOr([text:bar,
spanNear([text:tropical, text:cyclone], 0, true)])], 0, true))^10.0) " +
"(((text:\"foo a\")^5.0) ((text:\"a b\")^5.0) ((text:\"b tropical\")^5.0))
(spanOr([text:bar, spanNear([text:tropical, text:cyclone], 0, true)]))^5.0))" +
"(((text:\"foo a b\")^8.0) ((text:\"a b tropical\")^8.0) ((spanNear([text:b,
spanOr([text:bar, spanNear([text:tropical, text:cyclone], 0, true)])], 0,
true))^8.0))", q.toString());
}
N.B. The second part is failing for pf2, because for the query "foo a b
tropical cyclone" , pf2 is generating just :
((text:\"foo a\")^5.0) ((text:\"a b\")^5.0) ((text:\"b tropical\")^5.0)), which
I believe is incorrect as an additional span query should be generated (
(spanOr([text:bar, spanNear([text:tropical, text:cyclone], 0, true)]))^5.0)).
I will investigate further in the next days, just wanted to post it here to the
community attention :)
