Here's my finding on the \_timestamp field. curl -XPOST 'localhost:9200/bam' -d '{ "mappings" : { "_default_" : { "\_timestamp": { "enabled" : true } } } } }' curl -XPOST 'localhost:9200/bam/bam/' -d '{ "bam" : "bam" }' curl 'localhost:9200/bam/\_search?fields=\_source,\_timestamp&pretty' { "took" : 1, "timed\_out" : false, "\_shards" : { ``` "total" : 5, "successful" : 5, "failed" : 0 ``` }, "hits" : { ``` "total" : 1, "max_score" : 1.0, "hits" : [ { "_index" : "bam", "_type" : "bam", "_id" : "DREzT5VFTe2aJQC5ZRQb2g", "_score" : 1.0, "_source" : { "bam" : "bam" ``` } ``` } ] ``` } } curl -XPOST 'localhost:9200/bambam' -d '{ "mappings" : { "_default_" : { "\_timestamp": { "enabled" : true, "store" : true } } } } }' curl -XPOST 'localhost:9200/bambam/bambam/' -d '{ "bambam" : "bambam" }' curl 'localhost:9200/bambam/\_search?fields=\_source,\_timestamp&pretty' { "took" : 1, "timed\_out" : false, "\_shards" : { ``` "total" : 5, "successful" : 5, "failed" : 0 ``` }, "hits" : { ``` "total" : 1, "max_score" : 1.0, "hits" : [ { "_index" : "bambam", "_type" : "bambam", "_id" : "bDa7LxPBRQaPnoxj6R96dw", "_score" : 1.0, "_source" : { "bambam" : "bambam" ``` }, ``` "fields" : { "_timestamp" : 1392089217844 } } ] ``` } } Is this what you're seeing? I guess timestamp is being "stored" somewhere in order for facet and query to work. But it is unexpected that without store: true, that no timestamps are returned in result. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Why it's unexpected? If a field is not stored, you can not retrieve it. What's wrong with that? -- David 😉 Twitter : @dadoonet / @elasticsearchfr / @scrutmydocs Le 11 févr. 2014 à 04:34, Khoa Nguyen [huu.khoa.nguyen@gmail.com](mailto:huu.khoa.nguyen@gmail.com) a écrit : Here's my finding on the \_timestamp field. curl -XPOST 'localhost:9200/bam' -d '{ "mappings" : { "_default_" : { "\_timestamp": { "enabled" : true } } } } }' curl -XPOST 'localhost:9200/bam/bam/' -d '{ "bam" : "bam" }' curl 'localhost:9200/bam/\_search?fields=\_source,\_timestamp&pretty' { "took" : 1, "timed\_out" : false, "\_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 1, "max\_score" : 1.0, "hits" : [ { "\_index" : "bam", "\_type" : "bam", "\_id" : "DREzT5VFTe2aJQC5ZRQb2g", "\_score" : 1.0, "\_source" : { "bam" : "bam" } } ] } } curl -XPOST 'localhost:9200/bambam' -d '{ "mappings" : { "_default_" : { "\_timestamp": { "enabled" : true, "store" : true } } } } }' curl -XPOST 'localhost:9200/bambam/bambam/' -d '{ "bambam" : "bambam" }' curl 'localhost:9200/bambam/\_search?fields=\_source,\_timestamp&pretty' { "took" : 1, "timed\_out" : false, "\_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 1, "max\_score" : 1.0, "hits" : [ { "\_index" : "bambam", "\_type" : "bambam", "\_id" : "bDa7LxPBRQaPnoxj6R96dw", "\_score" : 1.0, "\_source" : { "bambam" : "bambam" }, "fields" : { "\_timestamp" : 1392089217844 } } ] } } Is this what you're seeing? ## I guess timestamp is being "stored" somewhere in order for facet and query to work.
