Not that I know of. The DataImportHandler has the ability to create multiple documents from one input stream. It is possible to create a DIH file that reads large log files and splits each one into N documents, with the file name as a common field. The DIH wiki page tells you in general how to make a DIH file.
http://wiki.apache.org/solr/DataImportHandler >From this, you should be able to make a DIH file that puts log files in as separate documents. As to splitting files up into mini-documents, you might have to write a bit of Javascript to achieve this. There is no data structure or software that implements structured documents.
