Hi - trying to execute a search in Lucene and getting results I don't
understand :(
The index contains fields search_text and type - both indexed tokenized.
I'm attempting to execute the query:
+(search_text:austell~0.9 search_text:ga~0.9) +(type:1 type:4)
And expect to match document 156297 (search_text=="Austell GA", type==1).
I am executing this query both directly in code and via the tool Luke - but
getting WILDLY different answers. In Luke, the expected document is found
no problem, but in my own code I find no results. Obviously I suspect my
code of being crap ;)
Oh, FYI, in both my local code and Luke I am using a StandardAnalyzer and
the default column is "search_text".
Here's what I'm doing:
/******************************************************************/
File location = new File("/the/correct/path");
IndexReader index = IndexReader.open(location);
Searcher searcher = new IndexSearcher(index);
QueryParser parser = new QueryParser("search_text", new
StandardAnalyzer());
Query query = parser.parse("+(search_text:austell~0.9 search_text:ga~0.9)
+(type:1 type:4)");
System.out.println(searcher.explain(query, 156296));
/******************************************************************/
When I run this, I get:
| 0.0000 = (NON-MATCH) Failure to meet condition(s) of required/prohibited
clause(s)
| 0.0000 = no match on required clause (() ())
| 0.0000 = (NON-MATCH) product of:
| 0.0000 = (NON-MATCH) sum of:
| 0.0000 = coord(0/2)
| 0.2133 = (MATCH) product of:
| 0.4267 = (MATCH) sum of:
| 0.4267 = (MATCH) weight(type:1 in 156296), product of:
| 0.3672 = queryWeight(type:1), product of:
| 1.1618 = idf(docFreq=315734, numDocs=371197)
| 0.3161 = queryNorm
| 1.1618 = (MATCH) fieldWeight(type:1 in 156296), product of:
| 1.0000 = tf(termFreq(type:1)=1)
| 1.1618 = idf(docFreq=315734, numDocs=371197)
| 1.0000 = fieldNorm(field=type, doc=156296)
| 0.5000 = coord(1/2)
So obviously I'm loading the index (since it did match the "type") - but it
seems to be COMPLETELY ignoring the criteria on "search_text".
When I run this exact same string in Luke, I get:
| 8.0079 = (MATCH) sum of:
| 7.9578 = (MATCH) sum of:
| 5.4904 = (MATCH) weight(search_text:austell in 156297), product of:
| 0.8074 = queryWeight(search_text:austell), product of:
| 10.8800 = idf(docFreq=18, numDocs=371197)
| 0.0742 = queryNorm
| 6.8000 = (MATCH) fieldWeight(search_text:austell in 156297),
product of:
| 1.0000 = tf(termFreq(search_text:austell)=1)
| 10.8800 = idf(docFreq=18, numDocs=371197)
| 0.6250 = fieldNorm(field=search_text, doc=156297)
| 2.4673 = (MATCH) weight(search_text:ga in 156297), product of:
| 0.5413 = queryWeight(search_text:ga), product of:
| 7.2936 = idf(docFreq=685, numDocs=371197)
| 0.0742 = queryNorm
| 4.5585 = (MATCH) fieldWeight(search_text:ga in 156297), product of:
| 1.0000 = tf(termFreq(search_text:ga)=1)
| 7.2936 = idf(docFreq=685, numDocs=371197)
| 0.6250 = fieldNorm(field=search_text, doc=156297)
| 0.0501 = (MATCH) product of:
| 0.1002 = (MATCH) sum of:
| 0.1002 = (MATCH) weight(type:1 in 156296), product of:
| 0.0862 = queryWeight(type:1), product of:
| 1.1618 = idf(docFreq=315734, numDocs=371197)
| 0.0742 = queryNorm
| 1.1618 = (MATCH) fieldWeight(type:1 in 156296), product of:
| 1.0000 = tf(termFreq(type:1)=1)
| 1.1618 = idf(docFreq=315734, numDocs=371197)
| 1.0000 = fieldNorm(field=type, doc=156296)
| 0.5000 = coord(1/2)
Which while clearly looking at the same document ID in the same index is
conversely working perfectly!
Does anybody have any idea where I am screwing up? Thanks!
Casey
