Hi, In my application, I input only single term query (at one time) and get back the corresponding scorings for those queries. But I am little struggling of understanding Lucene scoring. I have reffered http://lucene.apache.org/java/2_4_0/api/org/apache/lucene/search/Similarity.html and some other pages to resolve my matters. But some are still remain.
1) Why it has taken the squareroot of frequency as the tf value and square of the idf vale in score function? 2) If I enter single term query, then what will return bythe coord(q,d)? Since there are always one term in the query, I think always it should be 1! Am I correct? 3) I am also struggling understanding sumOfSquaredWeights (in queryNorm(q)). As I can understand, this value depends on the nature of the query we input and depends on that, it uses different methods such as TermQuery, MultiTermQuery, BooleanQuery, WildcardQuery, PhraseQuery, PrefixQuery, etc. But if I always use single term query, then what will be the way selected by the system from above? If somebody can pls. help me to resolve these problems. Appreciate any reply from you. Regards, Manjula
