2 question about solr and lucene

2013-09-16 Thread Robin Wei 
Hi, guys:
I met two questions about solr and lucene, wish people to help out.
use payload query but can NOT with numerical field type.  for example:  
  
I implemented my own requesthandler, refer to 
http://hnagtech.wordpress.com/2013/04/19/using-payloads-with-solr-4-x/ 
 I query in solr:sinaTag:operate
  solr response:
  "numFound": 2,
"start": 0,
"maxScore": 99,
"docs": [
  {
"id": "1628209010",
"followersCount": 752,
"sinaTag": "operate|99 C2C|98 B2C|97 OnlineShopping|96 E-commercial|94",
"score": 99
   },
  {
"id": "1900546410",
"followersCount": 1002,
"sinaTag": "Startup|99 Benz|98 PublicRelation|97 operate|96 Activity|95 
Media|94 AD|93 Vehicle|92 ",
  "score":   96
   }
This work well. 
But query with combined with other numberical condition, such as:
sinaTag:operate and followersCount:[752 TO 752]
{
   "responseHeader": {
"status": 0,
"QTime": 40
  },
  "response": {
"numFound": 0,
"start": 0,
"maxScore": 0,
"docs": []
  }
}
According these dataset, the first record should be responsed rather than 
NOT FOUND. 
I not know why.


  2. About string field fuzzy match filtering, how to get the score? what the 
formula is?
 When I used two or several string fuzzy match, probable AND or OR,  how to 
get the score? what the formula is?
 Might I implement myself score formula class which interface or abstract 
class to extend ?
 



Thanks in advance.
