Hi  
I've noticed something strange when I do queries on ES cluster.

Basically my entire query is a string like this: headlights OR headlamp

So the JSON would look sth like this:  
"query\_string" : {  
"query" : "headlights OR headlamp",  
"default\_field" : "post.body"  
}  
}

Now the confusing part:  
1: If I search for headlights I get 10 results.  
2: If I search for headlamp I get 9 results.  
3: When I search for headlights OR headlamp I get 4 results. The results  
contain 2 results for headlights and 2 results for headlamp.  
_Shouldn't this return 10+9 results? Why not?_  
4: If I search for for headlights OR headlamp I get only 1 result. This is  
correct since there is one results with both these words.

Thanks  
Adrian

#4 is supposed to be AND not OR:

4: If I search for headlights AND headlamp I get only 1 result. This is  
correct since there is one results with both these words.
