Hi everyone, I need a filter to split in two words a word containing a suffix that belongs to a list (Maybe a text file containing all the suffix) but I can't find an existing filter doing that. Does anyone have a solution to this? If not, is there a way to write my own filter in Java and add it to ElasticSearch ? : ) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Off the top of my head, I cannot think of an existing filter that accomplishes that task. Creating a custom filter is easy. Simply creating a Lucene filter and create a plug-in around it.

I wonder if you could use a Pattern Tokenizer in that case??? > **[Pattern tokenizer | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-pattern-tokenizer.html)** -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs > Le 12 mars 2015 à 04:32, Ivan Brusic [ivan@brusic.com](mailto:ivan@brusic.com) a écrit : > > Off the top of my head, I cannot think of an existing filter that accomplishes that task. > > Creating a custom filter is easy.

Yes, that's an idea : ) Pattern Tokenizer seems to give the results I want but I don't know if it's possible to define patterns based on a list of specific words. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
