Yes, I failed to notice that the removal of the slash was yet another
instance of the analyzer transforming its input. But the bottom line is that
you must do 100% of the same steps that analysis performs. If in doubt, pass
your literals through the standard analyzer itself.

Subject: Re: QueryParser and BooleanQuery
I tried changing the case to lower case, but still the BooleanQuery doesn't
return any documents.
I see that the text "/blank" is converted to "blank" in the QueryParser.
But in BooleanQuery it remains the same. When I remove the forward slash
sign from the input string, I get the matched documents with BooleanQuery.
Does the Standard Analyzer does this stripping of special characters as
well?

The query parser/analyzer is lower-casing the query terms automatically.
You have to do the same with with terms for BooleanQuery -
Term("cs-method", "GET") should be "Term("cs-method", "get")".
StandardAnalyzer is doing the lower-casing.

Hi,
I have following dataset indexed in Lucene.
2010-04-21 02:24:01 GET /blank 200 120
2010-04-21 02:24:01 GET /US/registrationFrame 200 605
2010-04-21 02:24:02 GET /US/kids/boys 200 785
2010-04-21 02:24:02 POST /blank 304 56
2010-04-21 02:24:04 GET /blank 304 233
2010-04-21 02:24:04 GET /blank 500 567
2010-04-21 02:24:04 GET /blank 200 897
2010-04-21 02:24:04 POST /blank 200 567
2010-04-21 02:24:05 GET /US/search 200 658
2010-04-21 02:24:05 POST /US/shop 200 768
2010-04-21 02:24:05 GET /blank 200 347
I am querying it in two ways, first with QueryParser and other with
BooleanQuery.
*QueryParser version:*
Query q = new QueryParser(version, "cs-method", new
StandardAnalyzer(version)).**parse("cs-method:GET AND cs-uri:/blank");
*BooleanQuery version:*
BooleanQuery q = new BooleanQuery();
q.add(new TermQuery(new Term("cs-method", "GET"),
BooleanClause.Occur.SHOULD);
q.add(new TermQuery(new Term("cs-uri", "/blank"),
BooleanClause.Occur.SHOULD);
When I run the two version, I am able to match the documents with the
QueryParser version, but not with BooleanQuery. The output is as follows:
*QueryParser output:*
Total Number of Documents - 11
Query --> +cs-method:get +cs-uri:blank
Total Clues Found - 5
*BooleanQuery output:*
Total Number of Documents - 11
Query --> cs-method:GET cs-uri:/blank
Total Clues Found - 0
Does anybody know why the BooleanQuery doesn't return any documents while
QueryParser does? Also, how can I change the BooleanQuery to work for the
above case?
