Lucene: Indexsearcher: java.lang.UnsupportedOperationException

I get the following error message: java.lang.UnsupportedOperationException

with Lucene search method: topDocs = searcher.search(booleanQuery, null,
100);

I'm using an old version of Lucene: Lucene 2.4.1 (I cannot upgrade!)
Can you help me to understand why I get such error ?

thanks

Could you also print and send the entire stack-trace?
Also, the query.toString()
