I'd strongly recommend rolling your own ingest code. See Erick's superb: https://lucidworks.com/post/indexing-with-solrj/
You can easily get attachments via the RecursiveParserWrapper, e.g. https://github.com/apache/tika/blob/master/tika-parsers/src/test/java/org/apache/tika/parser/RecursiveParserWrapperTest.java#L351 This will return a list of Metadata objects; the first one will be the main/container, each other entry will be an attachment.
