Hi all,  
i'm an elasticsearch's newbie.

I've a little problem about duplicate content in order to guess if an item  
must be inserted or updated.

Example:

- A car contains a brand, a model, a color, ... (max 10 criterias)
- in order to know if a record exists into ES, we use an algorithm with  
points system
- so if the brand exists, we count 1 point. If the brand and the model  
exist, we count 5 points, etc.
- after the search, we do a sum. If the total is high, we need to merge the  
record, otherwise, we create it.

I tried a method with bool/should match and top score but it took very long  
time (more than 2 seconds) to retrieved the datas for 8 bool term.

Do you have a better idea about my problem ? Thanks in advance for your  
help and sorry for my bad english !
