tnx. and my main question is about maxBooleanDefault in solr config. it is 1024 by default. and i have a edismax query with about 500 words in this way: q1= str1 OR str2 OR str3 ...OR strn it throws exception that cant't parse query too boolean clause. so if i changed maxBooleanDefault to 1500 it works but some thing is ambiguous for me is when i don;t change maxBooleanDefault and it remains 1024. but i changed query in this way q2 = str1 str2 str3 ... strn // i eliminated OR between for and inside space i didn't get exception !!! why?! what is diffrence between q1 an q2??
