Code:  
TermsFacetBuilder facetBuilder = new  
TermsFacetBuilder("prefix").field("prefix");  
facetBuilder.size(10000);  
facetBuilder.facetFilter(boolFilter);  
facetBuilder.regex("^[a-z]",Pattern.DOTALL);

the result still contains prefix in [a-z], but if I change size from  
10000 to 1000, it works.

very weird~
