i have the same problem but with doktype=254(sysfolder) for indexing my tt_news table.

just added  this to typoscript configuration of the root page

tx_crawler.crawlerCfg.paramSets {
  tt_news = &tx_ttnews[tt_news]=[_TABLE:tt_news;_PID:101]
  tt_news.procInstrFilter = tx_indexedsearch_reindex, tx_cachemgm_recache
  tt_news.cHash = 1
  tt_news.pidsOnly = 147
}

and launched the crawling process from the root page for infinite level.
The News sysfolder dosn't be crawled
