RE: Test failure question
Hi,
testBarelyCloseEnough(), testExact(), testMulipleTerms(),
etc? If so, then the NUnit is not doing this. I tested by
outputing to stdout.
NUnit calls setUp before each test and calls tearDown after each test.
Add Console.WriteLine and see the result.
Let me show:
--
[TestFixture]
public class TestPhraseQuery{
[SetUp]
protected void SetUp() {
directory = new RAMDirectory();
IndexWriter writer = new IndexWriter(directory, new
WhitespaceAnalyzer(), true);
...
Console.WriteLine(set up);
}
[TearDown]
protected void TearDown() {
searcher.Close(); directory.Close();
Console.WriteLine(tear down);
}
[Test]
public void TestNotCloseEnough() {
query.SetSlop(2);
.
MockAssert.AreEqual(0, hits.Length());
Console.WriteLine(not close);
}
--
The output:
---
set up
barely
tear down
set up
tear down
...

RE: Test corpus
Hi, From: Marvin Humphrey [mailto:[EMAIL PROTECTED] I'm looking for a test corpus to use for some benchmarking and parsing tests. I can whip one up myself, but it would be nice to use something standardized. I'd like something that doesn't require a license/fee, so that other people can run the same tests. At least 1000 docs, a few hundred words each. Any suggestions?

LUCENE-460
Hi, Question about latest cvs changes and hashcodes. http://issues.apache.org/jira/browse/LUCENE-460 Could anybody explain the magic numbers? 0x6634D93C,0x2742E74A and other. Any special meaning?

RE: Advanced query language
Hi,
From: Erik Hatcher [mailto:[EMAIL PROTECTED]
MoreLikeThis minNumberShouldMatch=3
maxQueryTerms=30
We're back to MoreLikeThis - it's not currently a Query subclass.
How do you envision this sort of thing fitting in if it's not a Query?
But MoreLikeThis class produces a Query. It's similar to google define:
search.
I think goolge handle such queries and then redirect search to somewhere.
And QueryParser can handle such searches too and use an alternative logic to
create Query.
For example, we can extend the QueryParser by special (syntax) handlers
which will be create the Query.
Something lke this:
--
class LikeHandler {};
LikeHandler likeHandler = new LikeHandler(...);
string queryString = like:(red quick fox);
Query q = QueryParser.parse(queryString, analyzer, likeHandler);
--
QueryParser scan the input, find special command (like:) and then find the
handler for this command.
If the handler exists the QP call it to create the Query.
Disadvantages are present.

RE: Advanced query language
Hi, From: markharw00d [mailto:[EMAIL PROTECTED] Re: MoreLikeThis queries. Yes, they can be usefully wrapped as queries (see attached simple example). In fact it was my attempts at bastardising QueryParser to support them that brought home it's limitations. I ended up with a subclass hack that (mis)used the field name to parse a query string like:123 where 123 was a doc id. With the QueryParser syntax I was not able to pass other parameters which MoreLikeThis could usefully use to control the behaviour of this query type eg choice of fieldname(s) used, max number of terms generated, minNumberShouldTerms to match etc etc. With the _current_ QP syntax. In refer to my previous letter about syntax handlers you would be able to pass the parameters to handler. string query = like(param1, param2,...): (bla-bla-bla); A syntax of parameters isn't signifant to QP. QP do not need to know anything about parameter's syntax. string query=like(percentTermsToMatch=0.25f,docId=44,...):... ; Or string query=like(0.25f,44): ... This is not unusual, each query type has potentially multiple optional parameters that tweak it's behaviour. If I don't have a query language that names the parameters explicitly (say, XML) I end up having to define what looks like a function with a long list of parameters: like (123,,,4,,,). Ack. Exactly.
