在elasticsearch中对数据进行聚合，想得出每个来源的数据量，mapping:
"news_source": {
"type": "text"
},
"related_freq": {
"type": "integer"
},
查询条件:
GET /event_news/_search
{
"size": 0,
"aggs": {
"news_source_info":{
"terms": {
"field": "news_source"
},
"aggs": {
"total_sum": {
"sum": {"field": "related_freq"}
}
}
}
}
}
结果报错
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [news_abstract] 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": [
