Subject Re: Scoring for specific field queries
Date Fri, 09 Oct 2009 07:02:27 GMT
Avlesh,
I don't see anything wrong with the data from analysis.

KeywordTokenized:

*term position ** **1** **2** **3** **4** **5** **6** **7** **8** **9** **10
** **11** **12** **13** **14** **15** **16** **...*
*term text ** **th** **he** **e ** **c** **ch** **ha** **am** **mp** **pi**
**io** **on** **the** **he ** **e c** **ch** **cha** **...*
*term type ** **word** **word** **word** **word** **word** **word** **word**
**word** **word** **word** **word** **word** **word** **word** **word** **
word** **...*
*source start,end ** **0,2** **1,3** **2,4** **3,5** **4,6** **5,7** **6,8**
**7,9** **8,10** **9,11** **10,12** **0,3** **1,4** **2,5** **3,6** **...*

WhitespaceTokenized:

*term position ** **1** **2** **3** **4** **5** **6** **7** **8** **9** **10
** **11** **...*
*term text ** **th** **he** **the** **ch** **ha** **am** **mp** **pi** **io*
* **on** **cha** **...*
*term type ** **word** **word** **word** **word** **word** **word** **word**
**word** **word** **word** **word** **...*
*source start,end ** **0,2** **1,3** **0,3** **0,2** **1,3** **2,4** **3,5**
**4,6** **5,7** **6,8** **...*

Is term position considered during scoring?

Thanks,
Rih
