Wrong ordering
Hi All,
I have one basic query. Below given is the output of my query with debug
status on. In my result i get document with lowest score comes above the
document with highest score. So my document is returned in the order as
follows
Doc1 (scoring 12.52)
Doc2 (scoring 2.52)
Doc3 (scoring 254)
Could anyone let me know is there any factor which can affect the ordering?
I am sure that I didn't specify any sorting techniques.
12.52 = (MATCH) sum of:
12.52 = (MATCH) product of:
25.04 = (MATCH) sum of:
25.04 = (MATCH) max plus 0.01 times others of:
4.0 = (MATCH) weight(content:cup^4.0 in 497), product of:
4.0 = queryWeight(content:cup^4.0), product of:
4.0 = boost
1.0 = idf(docFreq=272, maxDocs=85126)
1.0 = queryNorm
1.0 = (MATCH) fieldWeight(content:cup in 497), product of:
1.0 = tf(termFreq(content:cup)=1)
1.0 = idf(docFreq=272, maxDocs=85126)
1.0 = fieldNorm(field=content, doc=497)
25.0 = (MATCH) weight(title:cup^25.0 in 497), product of:
25.0 = queryWeight(title:cup^25.0), product of:
25.0 = boost
1.0 = idf(docFreq=14, maxDocs=85126)
1.0 = queryNorm
1.0 = (MATCH) fieldWeight(title:cup in 497), product of:
1.0 = tf(termFreq(title:cup)=1)
1.0 = idf(docFreq=14, maxDocs=85126)

nothing about your question makes it clear if you are using Solr or
Lucene-Java directly.
If you are using Solr, then we need to know what your request URL looks
like, and how your request handler is configured.
If you are using Lucene-Java then we need to see the code you are using to
execute the search.
One extremeley simple explanation might be that you aren't sorting on
score -- but that's just a shot i nthe dark given the limited info you
have provided about how you are getting these results.
