I\'ve two sets of search indexes. TestIndex (used in our test environment) and ProdIndex(used in PRODUCTION environment). Lucene search query: +date:[20090410184806 TO 200910071
I had this same issue in C# code running with the Sitecore web content management system. I used Randy's answer above, but was not able to use the System get and set property functionality. Instead I retrieved the current count, incremented it, and set it back. Worked great!
catch (BooleanQuery.TooManyClauses e)
{
// Increment the number of boolean queries allowed.
// The default is 1024.
var currMaxClause = BooleanQuery.GetMaxClauseCount();
var newMaxClause = currMaxClause + 1024;
BooleanQuery.SetMaxClauseCount(newMaxClause);
retry = true;
}
