This ticket will add the *split* parameter which will add a > top level split by categorical field, to produce time lines per each split. > The limit parameter will also be added and be applied only to split. The sort > will always be desc on the first aggregation in the first iteration to keep > the parameters simple. > Sample syntax: > {code} > timeseries(collection1, > q="*:*", > field="timefield", > split="company", > limit="10", > gap="+1DAY", > format="YYYY-dd-MM" , > avg(price_f)) > {code} > The output of this can be easily pivoted into a matrix and correlated or > clustered like the output of the *facet2D* function. The *diff* and > *minMaxScale* functions already support operations over matrix rows so it's > very easy to perform clustering etc.. on this output. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
