Hello,
I have added an aggregated field that is configured to be a union aggregation to the search index. No search results are generated and I get this error:
Elasticsearch\Common\Exceptions\BadRequest400Exception: {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Fielddata is disabled on text fields by default. Set fielddata=true on [tags] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."}],"type":"search_phase_execution_exception","reason":"all shards failed","phase":"query","grouped":true,"failed_shards":
It appears that the field type should either be keyword or text with fielddata=true enabled.
Here is the field that is generated in the index:
"tags" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},Setup the index:
Create an index with a General Aggregated Field that is a Union type.
Once added to the fields, ensure that it is a Fulltext type.
Build the index.
Build the View:
Create a view that has a keyword search filter and add the field you create above to it.
Try and search for a value that is in either field you aggregated into one (the one you added to the index)
At this point you should make two observations:
It appears that you can't switch field types after the index has been built. If i set fielddata=true, the search works and the error goes away.
curl -X PUT "YOUR_SERVER:9200/YOUR_INDEX/_mapping/_doc?pretty" -H 'Content-Type: application/json' -d'
{
"properties": {
"YOUR FIELD": {
"type": "text",
"fielddata": true
}
}
}
'It seems like elastic search would prefer the fieldtype to be keyword for performance reasons over a fielddata enabled text.

Index time boost is deprecated. Using Elasticsearch 8.x this results in errors.
To avoid conflicts while applying both the patch from

and this patch, I've rerolled the patch from #3 to incorporate both changes and added an interdiff.
