I want to specify my own stop-words. This is what I found so far:  
[http://www.elasticsearch.org/guide/reference/index-modules/analysis/stop-tokenfilter.html](http://www.elasticsearch.org/guide/reference/index-modules/analysis/stop-tokenfilter.html)  
In elasticsearch.yml I'd have such analyzer specified:

index :  
analysis:  
analyzer:  
string\_lowercase:  
tokenizer : keyword  
filter : lowercase  
stopwords\_path : stopwords.txt  
ignore\_case : true

How should I specify the stop-words in the stopwords.txt file? Just a  
word in a line, or somehow else?

Also, I don't care which language users will use to index data, so if  
I'd put stopwords from different languages into the same file, it  
should be no problem, but should I use just UTF-8 encoding, or should  
I use encoding like we use in .properties files, e.q. "de art  
\u00edculos"?

Thank you,  
Eugene S.

Each stop word should be in its own "line" (separated by \n). The file is  
read in UTF8 format.
