Subject [jira] [Commented] (SOLR-10085) Streaming Expressions result-set fields not in order
Date Wed, 01 Feb 2017 16:56:51 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10085?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848623#comment-15848623

Kevin Risden commented on SOLR-10085:
-------------------------------------

One thought I had but haven't tested is does the fl parameter allow for specifying the order
of fields? Is it possible that fl would work with the streaming expression?

> I'm trying out the Streaming Expressions in Solr 6.3.0. 
> Currently, I'm facing the issue of not being able to get the fields in the result-set
to be displayed in the same order as what I put in the query.
> For example, when I execute this query:
>  http://localhost:8983/solr/collection1/stream?expr=facet(collection1,
>       q="*:*",
>       buckets="id,cost,quantity",
>       bucketSorts="cost desc",
>       bucketSizeLimit=100,
>       sum(cost), 
>       sum(quantity),
>       min(cost), 
>       min(quantity),
>       max(cost), 
>       max(quantity),
>       avg(cost), 
>       avg(quantity),
>       count(*))&indent=true
> I get the following in the result-set.
>    {
>   "result-set":{"docs":[
> 	{
>     "min(quantity)":12.21,
>     "avg(quantity)":12.21,
>     "sum(cost)":256.33,
>     "max(cost)":256.33,
>     "count(*)":1,
>     "min(cost)":256.33,
>     "cost":256.33,
>     "avg(cost)":256.33,
>     "quantity":12.21,
>     "id":"000001",
>     "sum(quantity)":12.21,
>     "max(quantity)":12.21},
> 	{
>     "EOF":true,
>     "RESPONSE_TIME":359}]}}
> The fields are displayed randomly all over the place, instead of the order sum, min,
max, avg as in the query. This may cause confusion to user who look at the output.  Possible
improvement to display the fields in the result-set in the same order as the query
