ChainedFilter

[Bhavin Pandya <bh...@rediff.co.in>]

Hi,

I am using ChainedFilter and FilteredQuery together in order to remove RangeQuery from my code.
the problem is its not working..its effect is not coming...it returns me same number of record whether i am including range or not.
Here is the snippet.


                    BooleanQuery bqone = "coming from parent function; it booleanQuery of few termsQuery"
                    RangeFilter rf[] = new RangeFilter[2];
                    rf[0]=new RangeFilter("RANGEFIELD1", 20, 30 , true,true);
                    rf[1]=new RangeFilter("RANGEFIELD2", 20, 30 , true,true);
                    isChanged = true;

                    ChainedFilter cf = new ChainedFilter(rf,ChainedFilter.AND);
                    fq=new FilteredQuery(bqone,cf);
                    
                    Hits hits = searcher.search(fq); 


Actually data is splitted across two columns ( RANGEFIELD1 and RANGEFIELD2 ) on which i want to fire range. e.g give me all records which is between 20 and 30.
so i have created two filter and passed it to chainedfilter...
but its not working ...i dont know what i m missing.... is there any better way to implement this...?

Thanks.

Hi guys,

Its is solved now....
I come to know that "If you are ANDing/ORing FilteredQuery with say 
BooleanQuery then Its not giving proper result so i added that BooleanQuery 
before creating FilteredQuery"
May be i am wrong...but i changed the sequence of my queries ...and now its 
working...
