Hi,

Do I need to apply re-indexing if I update the keywords file and I need it to consider the updated file?

Best,

Maryam

Words that shouldn't be stemmed.  
I used the keyword marker.

Could you provide a full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will help to better understand what you are doing. Please, try to keep the example as simple as possible.

A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.

I don't have any problems with the code.  
I have the following scenario:  
I created my index with a keyword marker provided with a file containing a list of words (those that shouldn't be stemmed).  
This file is updated regularly, so I was asking if I need to apply re-indexing so that the index considers the updated keywords file.

```
 .Settings(ss => ss
                    .Analysis(an => an
                        .TokenFilters(tf => tf
                            .Stop("arabic_stop", ts => ts
                                .StopWords("_arabic_"))
                            .KeywordMarker("ar_keywords", km => km.KeywordsPath(keywordsFile))
                            .Stemmer("arabic_stemmer", st => st
                                .Language("arabic"))
                        )
                        .Analyzers(ns => ns
                            .Custom("ar_analyzer", cm => cm
                                .Tokenizer("standard")
                                .Filters("arabic_stop", "ar_keywords", "arabic_normalization", "arabic_stemmer")
                            )
                            .Custom("ar_standard", cm => cm
                                .Tokenizer("standard")
                                .Filters("arabic_normalization")
                            ))
                    )
                )
```

Ok. So you are talking about [https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-keyword-marker-tokenfilter.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-keyword-marker-tokenfilter.html)

So yes you need to reindex you data if you don't want those terms to be modified at index time.
