How to manage token filters in ElasticSearch

An attempt to control the order in which markers are used in ElasticSearch.

I know from the documents that the tokenizer is applied first, then the token filters, but they do not mention how the order of the marker filters is determined.

Here is a YAML snippet from my script analysis setup:

       KeywordNameIndexAnalyzer :
           type : custom
           tokenizer : whitespace
           filter : [my_word_concatenator, keyword_ngram]

I would have thought it my_word_concatenatorwould apply before keyword_ngram, but it seems like it is not. Does anyone know how (or if) the order of these filters can be controlled?

Thank you so much!
