If you are not installing the latest version, follow the links in the table to see installation instructions for the old version.
To install the plugin, run the command depending on your ES installation:
bin/elasticsearch-plugin install https://github.com/EvidentSolutions/elasticsearch-analysis-raudikko/releases/download/v0.1/elasticsearch-analysis-raudikko-0.1-es7.3.2.zip
bin/elasticsearch-plugin install https://github.com/EvidentSolutions/elasticsearch-analysis-raudikko/releases/download/v0.1/elasticsearch-analysis-raudikko-0.1-es7.10.0.zip
bin/elasticsearch-plugin install https://github.com/Lamia/elasticsearch-analysis-raudikko/releases/download/v0.1/elasticsearch-analysis-raudikko-0.1-es7.10.2.zip
After installing the plugin, you can quickly verify that it works by executing:
curl -XGET 'localhost:9200/_analyze' -H 'Content-Type: application/json' -d '
{
"tokenizer" : "finnish",
"filter" : [{"type": "raudikko"}],
"text" : "Testataan raudikon analyysiä tällä tavalla yksinkertaisesti."
}'
If this works without error messages, you can proceed to configure the plugin index.
Include finnish tokenizer and raudikko filter in your analyzer, for example:
{
"index": {
"analysis": {
"analyzer": {
"default": {
"tokenizer": "finnish",
"filter": ["lowercase", "raudikkoFilter"]
}
},
"filter": {
"raudikkoFilter": {
"type": "raudikko"
}
}
}
}
}You can use the following filter options to customize the behaviour of the filter:
| Parameter | Default value | Description |
|---|---|---|
| analyzeAll | true | Use all analysis possibilities or just the first |
| minimumWordSize | 3 | minimum length of words to analyze |
| maximumWordSize | 100 | maximum length of words to analyze |
| analysisCacheSize | 1024 | number of analysis results to cache |
This plugin supersedes elasticsearch-analysis-voikko and
is fully compatible with it (it provides a filter named voikko as a compatibility measure). Therefore, you can remove
the old plugin from your Elasticsearch installation and replace it with this plugin without having to reindex anything.
Just make sure to uninstall the old plugin bin/elasticsearch-plugin remove elasticsearch-analysis-voikko when installing
this one in place.
