Hi Guys, Would it make sense to set "doc\_values: enabled" on a murmur3 type field since it’s being used for aggregations? - Drew -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Here's some info on doc values [http://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html#\_enabling\_doc\_values](http://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html#_enabling_doc_values) I'm not sure what a murmur3 field is though, I can see what it is but how does that relate to ES?

Hi Mark, Thanks for the reply, but I already know what doc\_values are. I wanted to see if there is a benefit to setting murmur3 type (which actually extends long type) to doc\_values when it comes to doing cardinality aggregations. - Drew > On Mar 25, 2015, at 5:17 PM, Mark Walkom [markwalkom@gmail.com](mailto:markwalkom@gmail.com) wrote: > > Here's some info on doc values [http://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html#\_enabling\_doc\_values](http://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html#_enabling_doc_values) [http://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html#\_enabling\_doc\_values](http://www.elastic.co/guide/en/elasticsearch/guide/current/doc-values.html#_enabling_doc_values) > > I'm not sure what a murmur3 field is though, I can see what it is but how does that relate to ES? > > On 26 March 2015 at 10:28, Drew Kutcharian \<[drew@venarc.com](mailto:drew@venarc.com) [mailto:drew@venarc.com](mailto:drew@venarc.com)\> wrote: > Hi Guys, > > Would it make sense to set "doc\_values: enabled" on a murmur3 type field since it’s being used for aggregations? > > - Drew > > -- > You received this message because you are subscribed to the Google Groups "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com) [mailto:elasticsearch%2Bunsubscribe@googlegroups.com](mailto:elasticsearch%2Bunsubscribe@googlegroups.com). > To view this discussion on the web visit [https://groups.google.com/d/msgid/elasticsearch/34629D7E-3B3C-4B18-B13E-5A689792CFE8%40venarc.com](https://groups.google.com/d/msgid/elasticsearch/34629D7E-3B3C-4B18-B13E-5A689792CFE8%40venarc.com) [https://groups.google.com/d/msgid/elasticsearch/34629D7E-3B3C-4B18-B13E-5A689792CFE8%40venarc.com](https://groups.google.com/d/msgid/elasticsearch/34629D7E-3B3C-4B18-B13E-5A689792CFE8%40venarc.com). > For more options, visit [https://groups.google.com/d/optout](https://groups.google.com/d/optout) [https://groups.google.com/d/optout](https://groups.google.com/d/optout). > > -- > You received this message because you are subscribed to the Google Groups "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com) [mailto:elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > To view this discussion on the web visit [https://groups.google.com/d/msgid/elasticsearch/CAEYi1X-oVq4gGahpU3ymvTR095gZtXsPxe4wY12y0S5yA%2BT9PQ%40mail.gmail.com](https://groups.google.com/d/msgid/elasticsearch/CAEYi1X-oVq4gGahpU3ymvTR095gZtXsPxe4wY12y0S5yA%2BT9PQ%40mail.gmail.com) [https://groups.google.com/d/msgid/elasticsearch/CAEYi1X-oVq4gGahpU3ymvTR095gZtXsPxe4wY12y0S5yA%2BT9PQ%40mail.gmail.com?utm\_medium=email&utm\_source=footer](https://groups.google.com/d/msgid/elasticsearch/CAEYi1X-oVq4gGahpU3ymvTR095gZtXsPxe4wY12y0S5yA%2BT9PQ%40mail.gmail.com?utm_medium=email&utm_source=footer). > For more options, visit [https://groups.google.com/d/optout](https://groups.google.com/d/optout) [https://groups.google.com/d/optout](https://groups.google.com/d/optout). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I'm answering my own question here since I came across this issue on GitHub. > > > I don't think we should allow trappy options like indexed=true or docvalues=fals…e for this field. Cardinality and range of values is enormous by definition. So the correct field options for a murmur3 field are: "index" : "no", "doc\_values" : true - Drew On Wednesday, March 25, 2015 at 4:28:25 PM UTC-7, Drew wrote: > Hi Guys, > > Would it make sense to set "doc\_values: enabled" on a murmur3 type field > since it’s being used for aggregations? > > - Drew -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
