required keyword in all a document

[KLessou]

Hi,

I would like to find all documents who contain "France, Flag, French".

I've got docs like this one :
<doc>
    <str name="id">...</str>
    <str name="k1_en">wordA,wordB,france, ...</str>
    <str name="k2_en">wordA,wordB,flag, ...</str>
    <str name="k3_en">wordA,wordB,french, ...</str>
    ...
</doc>

I can't make my query like this :
k1_en:(+france +flag +french)^100 OR k2_en:(+france +flag +french)^10 OR
k3_en:(+france +flag +french)

So, this only way to do what I want is to generate this query :

(k1_en:france^100 OR k2_en:france^10 OR k3_en:france)
AND
(k1_en:flag^100 OR k2_en:flag^10 OR k3_en:flag)
AND
(k1_en:french^100 OR k2_en:french^10 OR k3_en:french)

Is there a better/more simple way to do this ?

Thx in advance !
