with the current implementation the only way to achieve this is to 
prohibit the term in another clause for the excluded properties.

currently the text representation of a jcr:data property is indexed as 
part of the node scope fulltext index. but in some cases (such as yours) 
it is also desirable to have the fulltext index also on the jcr:data 
property. this however adds some overhead to the node indexing. I think 
in the end this is something that should be configurable because it is 
not always needed.

I've created an jira issue that describes this enhancement:

lucene has a max clauses limit of 1024. though, this can be set to a 
higher value. jackrabbit does not yet allow to configure this value.

wrt performance, the more clauses you have the longer the query will 
take to execute. in the end this completely depends on lucene. you might 
be able to find performance information on the lucene website.
