Retrieve index maxMergeDocs option

maxMergeDocs is a largest number of documents ever merged by addDocument().
Small values (e.g., less than 10,000) are best for interactive indexing,
as this limits the length of pauses while indexing to a few seconds.
Larger values are best for batched indexing and speedier searches.

Default value is PHP_INT_MAX

@return integer
@throws Zend_Search_Lucene_Exception
