Hello everyone,

I currently test indexing mult-language documents with combining ES basic analyze component. I want use additional english stemmer at korean, japanesem chinese analyzer for getting more wide search result of english. (english word appears in high probability all document)  
have you ever used [different from english script tokenizer, tokenfilters] + [english stemmer] combination?  
I tested some, and found no side-effect. It seems much distinguishable script and differ in unicode block.

please share your experiences.

thank you.

testing setting likes this,

"korean\_english": {  
"filter": [  
"trim",  
"arirang\_filter", (custom opensource)  
"decompounder",  
"delimiter",  
"lowercase",  
"english\_stop",  
"english\_stemmer"  
],  
"tokenizer": "arirang\_tokenizer" (custom opensource)  
},

`"japanese_filter" :{ "type":"custom", "tokenizer" : "kuromoji_tokenizer", (custom opensource) "filter" : ["kuromoji_baseform", "kuromoji_part_of_speech", "cjk_width", "stop", "english_stop", "delimiter", "kuromoji_stemmer", "english_stemmer", "lowercase"] }`

`"delimiter" :{ "type":"word_delimiter", "catenate_all" : true, "type_table_path" : "delimiterType.json", "type_table" : true, "split_on_numerics" : false },`

`"english_stemmer": { "type": "stemmer", "language": "english" }, "english_stop": { "type": "stop", "stopwords": "_english_" },`
