Hi! I was wondering if it's possible to apply tokenizer/analyzers to rank_feature fields. When attempting to create a sample index on ES 7.6.2 it doesn't appear to work, but I don't see anything explicit in the docs.
Index creation:
curl -X PUT \
http://127.0.0.1:9500/test/ \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/json' \
-H 'cache-control: no-cache' \
-d '{
"mappings": {
"properties": {
"topics": {
"type": "rank_features",
"analyzer": "path_analyzers"
}
}
},
"settings": {
"analysis": {
"analyzer": {
"path_analyzer": {
"tokenizer": "path_hierarchy"
}
}
}
}
}'
Response:
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "Mapping definition for [topics] has unsupported parameters: [analyzer : path_analyzers]"
}
],
"type": "mapper_parsing_exception",
"reason": "Failed to parse mapping [_doc]: Mapping definition for [topics] has unsupported parameters: [analyzer : path_analyzers]",
"caused_by": {
"type": "mapper_parsing_exception",
"reason": "Mapping definition for [topics] has unsupported parameters: [analyzer : path_analyzers]"
}
},
"status": 400
}
