Filter order influences results

Hey everybody!

For our elastic search implementation we use a custom analyzer looking like so:

  tokenizer: 'standard'
  filter: [ 'german_stop', 'english_stop', 'german_stemmer', 'english_stemmer', 'synonym', 'lowercase' ]
  char_filter: [ 'html_strip' ]

We use this for all languages on our site, thats why we have english and german filters in there.

I noticed that e.g. the lowercase filter only works if it is somewhere at the beginning of the array. In this order, I cant find the word Maxis if I search for maxis. Could somebody explain why that is?

Any explanation would be appreciated. Thank you guys
