Elasticsearch Highlight issue on aggregated fields
You have to set the highlight inside the top_hits aggregation properties (not inside of aggregation).
Here is a working minimal example:
echo create indexcurl -XPUT 'http://127.0.0.1:9010/files?pretty=1' -d '{ "settings": { }}'echo create typecurl -XPUT 'http://127.0.0.1:9010/files/_mapping/file?pretty=1' -d'{ "properties":{ "fileName":{ "type":"string", "term_vector":"with_positions_offsets" } }}'echo insert filescurl -XPUT 'http://127.0.0.1:9010/files/file/1?pretty=1' -d'{ "fileName":"quick brown fox"}'echo flushcurl -XPOST 'http://127.0.0.1:9010/files/_flush?pretty=1'echo search brown tophitscurl -XGET 'http://127.0.0.1:9010/files/file/_search?pretty=1' -d '{ "size" : 0, "query":{ "match":{ "fileName":"brown" } }, "aggregations" : { "docs" : { "top_hits" : { "highlight": { "fields": { "fileName": {} } } } } }}'
