Fulltext search in content return match in attributes ?

Hi,

When I am searching for nodes containing a spécific word in the content, the 
result set returns
some nodes where the match is included in an attribute value.

For example :
collection('/db/bv/rules/en_03')/dy:fragment/dy:content//P[. &= 'carriers']

returns

<P >
   <CLN > Livestock carrier </ CLN >
   , for ships specially intended to carry livestock. The additional 
requirements of
    <R REFID ="n000100050003" TYPEX ="R" GI ="CHAP" LABEL ="Chapter 3 Livestock 
carriers " > Part E, Chapter 3 </ R >
    are applicable to these ships.
</ P >

Is it normal ?

I do not put any index options in my conf.xml file in order to specify to index 
or not attributes.
Does putting /exist/indexer/index[@doctype='my-doctype']/@attributes to false 
may resolve
the problem ?
How to distinguish a fulltext search in content or in attributes ?
