Subject Re: Getting no hits ...
Date Thu, 23 Feb 2006 22:56:13 GMT
Follow up on my previous email ...

When I execute this query using luke using the standard analyzer on the 
same index, i get 8 hits.
 +(+content:eos\-20d) +entity:product +(title:"eos\-20d"~2^40.0 
((title:eos\-20d)^10.0) content:"eos\-20d"~2^20.0 (content:eos\-20d) 
categoryName:"eos\-20d"^80.0)

I modified my searching code to use the standard analyzer, but i did not 
get any hits back. I am still trying to figure out the problem out. Any 
ideas?
