Subject Possible to adjust FieldNorm?
Date Wed, 14 Dec 2011 09:50:01 GMT
Hi, 

Is it possible to adjust FieldNorm? I have a scenario where the search is
not producing the desired result because of fieldNorm:

Search terms: coaching leadership
Record 1: name="Ask the Coach", desc="...",...
Record 2: name="Coaching as a Leadership Development Tool Part 1",
desc="...",...

Record 1 was scored higher than record 2, despite record 2 has two matches.
The scoring is given below:

Record 1:
      1.2878088 = (MATCH) weight(name_en:coach in 6430), product of:
        0.20103075 = queryWeight(name_en:coach), product of:
          6.406029 = idf(docFreq=160, maxDocs=35862)
          0.03138149 = queryNorm
        6.406029 = (MATCH) fieldWeight(name_en:coach in 6430), product of:
          1.0 = tf(termFreq(name_en:coach)=1)
          6.406029 = idf(docFreq=160, maxDocs=35862)
          1.0 = fieldNorm(field=name_en, doc=6430)

Record 2:
      0.56341636 = (MATCH) weight(name_en:coach in 4744), product of:
        0.20103075 = queryWeight(name_en:coach), product of:
          6.406029 = idf(docFreq=160, maxDocs=35862)
          0.03138149 = queryNorm
        2.8026378 = (MATCH) fieldWeight(name_en:coach in 4744), product of:
          1.0 = tf(termFreq(crs_name_en:coach)=1)
          6.406029 = idf(docFreq=160, maxDocs=35862)
          0.4375 = fieldNorm(field=name_en, doc=4744)

Many thanks in advance.

Chut
