[TYPO3] crawler configuration

[Antonio Willybiro]

Hi there,
I have a site with many categories in different sys folders.
The craler page config i am currenltu using suggests that i have to create
one entry per sysfolder. Like that:
tx_crawler.crawlerCfg.paramSets {
  language = &L=[|_TABLE:pages_language_overlay;_FIELD:sys_language_uid]
  language.procInstrFilter =tx_indexedsearch_reindex, tx_cachemgm_recache,
tx_indexedsearch_crawler
  language.baseUrl = http://www.domain.com/

  news = &tx_ttnews[tt_news]=[_TABLE:tt_news;_PID:29]
  news {
  procInstrFilter = tx_indexedsearch_reindex, tx_cachemgm_recache
  cHash = 1
  pidsOnly = 19
  }
}

is there a way to have the crawler looking recursively in a main folder?

Regards,
Antonio
