Hello all,

I'm new with FS Crawler, so please be patient with me.

Using version 2.6, I'm crawling many files from a big Windows's folders tree. There are PDF, XLS, DOC, etc.

It's working, but the content attribute goes to Elasticsearch full of /t and /n characters.

```
  {
    "_index": "clgp-docs",
    "_type": "_doc",
    "_id": "c2c62de2f7d5af413ed074c845129751",
    "_score": 1.0,
    "_source": {
      "content": "\nHome\nHistória »\nSaudade\nSindipetro »\nDocumentos »\nSindicalize-se\n\n \n\nNotícias por base »\nEleição 2015 – 2018\nNotícias por assunto »\nBroncas do Petrolino\nAgenda da Diretoria\nTV Petroleira\n\nCategorizado | ACT, Agenda da Diretoria, Direitos, Petrobrás, Reuniões com RHs\n\nSindipetro-LP cobra soluções para problemas relacionados ao Benefício Educacional\n\nPostado em19 fevereiro 2016.\n\nO Benefício Educacional, uma das conquistas da categoria e importante ferramenta...  

```

Is it possible to change these special chars to space chars during the ingestion process? How to do it?

I aprecciatte if you could expose a \_setting.json example file.

Thanks

Welcome!

I believe that the only option from now is to use an ingest pipeline which does the removal at index time on elasticsearch side. See [https://fscrawler.readthedocs.io/en/latest/admin/fs/elasticsearch.html#using-ingest-node-pipeline](https://fscrawler.readthedocs.io/en/latest/admin/fs/elasticsearch.html#using-ingest-node-pipeline)

May be with this processor [https://www.elastic.co/guide/en/elasticsearch/reference/7.3/gsub-processor.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/gsub-processor.html)  
or this one [https://www.elastic.co/guide/en/elasticsearch/reference/7.3/script-processor.html](https://www.elastic.co/guide/en/elasticsearch/reference/7.3/script-processor.html)

Could you also open an issue in FSCrawler project so I can think about adding a regex parser in the future in FSCrawler itself?

Thanks about the ideia! I'll try it.

This would be a good improvement to the next versions os FS Crawler. I'll open a issue there, as you sugested.
