solr_group group.main

[jonasanso]

group.main should be a boolean following the doc

  \item{group.main}{(logical) If true, the result of the
  last field grouping command is used as the main result
  list in the response, using group.format=simple}

And should return the the group field in the main result

solr_group(q=':', group.field='journal', rows=5, group.limit=3, group.sort='publication_date desc', group.format='simple', group.main='true', fl='publication_date', url=url, key=key)
numFound start publication_date
1 889099 0 2014-01-17T00:00:00Z
2 889099 0 2014-01-17T00:00:00Z
3 889099 0 2014-01-17T00:00:00Z
4 889099 0 2014-01-16T00:00:00Z
5 889099 0 2014-01-16T00:00:00Z

Not sure now.

Maybe the response is correct but I don't understand it

> solr_group(q='*:*', group.field='journal', rows=5, group.limit=3, group.sort='publication_date desc', group.main='true' , raw = TRUE, fl='publication_date', url=url, key=key)

Hmm, I think group.main isn't working as expected, see this

http://api.plos.org/search/?q=ecology&group=true&group.field=journal&group.limit=3&fl=id,score&wt=json&group.format=grouped

versus this

http://api.plos.org/search/?q=ecology&group=true&group.field=journal&group.limit=3&fl=id,score&wt=json&group.format=grouped&group.main=true

Any thoughts on this @jonasanso ? If okay, I will close this issue

[jonasanso]

No idea Sckott. I close the issue.
