Can I specify regexp in stopwords for stop analyzer in elasticsearch?
Me again.. I don't seem to be able to add regexp to stopwords. However, I did manage to work around it by adding another filter called filter_amount. This is what it looks like:
"filter_amount": { "type": "pattern_replace", "pattern": "[\\d]+([\\.,][\\d]+)?", "replacement": "" }So this is what the settings should look like:
PUT /products{"settings": { "analysis": { "filter": { "my_stopwords": { "type": "stop", "stopwords": [ "l", "g" ] }, "filter_amount": { "type": "pattern_replace", "pattern": "[\\d]+([\\.,][\\d]+)?", "replacement": "" } }, "analyzer": { "my_analyzer": { "type": "custom", "tokenizer": "standard", "filter": [ "lowercase", "my_stopwords", "filter_amount"] }} }}}The rest is the same. Cheers!
