But If I issue following SQL: SELECT * FROM tab1 a JOIN tab2 b on a.ID = b.ID WHERE CONTAINS(a.*, @keystring) ...or: SELECT * FROM tab1 a JOIN tab2 b on a.ID = b.ID WHERE CONTAINS(b.*,@keystring) The performance is

Something similiar to this SQL query: SELECT DISTINCT(tags.value) FROM tags WHERE tags.key='some-key' I have came to this DSL so far: { "size": 0, "aggs": { "my_tags": { "nested": { "path": "tags" }, "aggs": { "filter" : { "terms": { "tags.key": "tag1" } }, "aggs": { "my
