Hi,

I am working on ES 6.3.X and I am using a external web crawler to crawl the data and when I check the index it has a lot of new line characters. Is there any suggestions to avoid the new line characters.

Why not solving that in your crawler directly?

I tried in my crawler but I have a limited resources on that. That's the reason I posted here whether any solution for that in elastic search side.

Hi,

You can look a filters to add to your mapping, in my project I have a filter like this one for special chars:

Doc: [https://www.elastic.co/guide/en/elasticsearch/reference/6.4/analysis-custom-analyzer.html#\_configuration\_8](https://www.elastic.co/guide/en/elasticsearch/reference/6.4/analysis-custom-analyzer.html#_configuration_8)

```
        "char_filter" : {
            "custom-quotes" : {
                "mappings" : [
                    "\\u0091=>\\u0027",
                    "\\u0092=>\\u0027",
                    "\\u2018=>\\u0027",
                    "\\u2019=>\\u0027",
                    "\\u201B=>\\u0027",
                    "\\uFF07=>\\u0027"
                ],
                "type" : "mapping"
            }
		}

```

bye,  
Xavier
