Strange problem when use dismax handler
Hi. All.
I am using default dismax to search within solr.
The problem is when I search I want to specify the "type" to restrict the
result.
Here is what I do:
1. Query String with one type (Works!)
((((:"design")) AND ((type:"product") )))
2. Query String with 2 types (Works!)
((((:"design")) AND ((type:"product") OR (type:"member"))))
3. Query String with 3 types (Works!)
((((:"design")) AND ((type:"product") OR (type:"member") OR (type:"forum")
)))
4. Query string with more than 3 types (doesn't work!)
((((:"design")) AND ((type:"product") OR (type:"member") OR (type:"forum")
OR (type:"stamp") OR (type:"answer") OR (type:"page"))))
Nothing was returned.
Don't know why. I think this should be caused by dismax setting, probably
mm (Minimum 'Should' Match)
But I have no idea how to configure it?
Please help. Thanks!
Regards.
Scott

Well. I figured it out.
I should use fq parameter.
&fq=type:music type:movie type:product

I use debugQuery to check my query url:
I notice the query url is parsed incorrectly.
The "type:book" was parsed as query string too. Sign~~~
+((+DisjunctionMaxQuery((keyword_level1:design^10.0 |
keyword_level2:design)~0.01) DisjunctionMaxQuery((keyword_level1:type^10.0 |
keyword_level2:type)~0.01) DisjunctionMaxQuery((keyword_level1:product^10.0
| keyword_level2:product)~0.01)
DisjunctionMaxQuery((keyword_level1:type^10.0 | keyword_level2:type)~0.01)
DisjunctionMaxQuery((keyword_level1:book^10.0 |
keyword_level2:book)~0.01))~3) ()
Then the question is how to specify the query filed , as in my case, type =
"book" besides use the "design" to search over 2 fields ?
Thanks
