Hi folks. I would like to develop for a searching system for Thai language. First of all, I found Thai analyzer and it seems like good. But It doesn`t meet my whole requirement so I would like to extends it. For example, I would like to add nGram token filter on the Thai analyzer. How to do this? Please, give me some advice. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, you can easily create custom analyzers, which use the thai analyzer and the ngram token filter.

OK. I also know about custom analyzer. But ThaiWordFilter is not aliased so I can`t use it. Alternatively, I can use following. But ThaiWordFilterFactory doesn`t have a zero-argument constructor so when I use a following setting, an error occurs. If I know how to use a factory which has an one-argument constructor or to extend based on ThaiAnalyzer, I can resolve this problem. { "analyzer": { "thai\_with\_ngram": { "type": "custom", "tokenizer": "standard", "filters": ["standard", "lowercase", "thai", "thai\_stop", "ngram"] } }, "filter": { "thai": { "type": "org.apache.lucene.analysis.th.ThaiWordFilterFactory" \<-- An error occurs because of lack of a zero-argument constructor. }, "thai\_stop": { "type": "stop", "stopwords\_path": "org/apache/lucene/analysis/th/stopwords.txt" }, "ngram": { your ngram configuration here } } } 2014년 2월 10일 월요일 오후 9시 45분 36초 UTC+9, Alexander Reelsen 님의 말: > Hey, > > you can easily create custom analyzers, which use the thai analyzer and > the ngram token filter.
