How to use facets with PySolr - can't seem to get facet results to show

Question

(I have seen similar questions to this - but cannot seem to resolve why the below doesnt work!)

Hi, I have a running local instance of solr and make the following call (via the url box in my browser):

http://localhost:8983/solr/select?q=video&rows=0&facet=true&facet.field=q_date

And get the results below (see results 1). Then I try the equivalent with Python/PySolr:

solr = pysolr.Solr('http://localhost:8983/solr/', timeout=10)

params = {
  'facet': 'true',
  'facet.field': 'q_date',
  'rows': '0',
}

results = solr.search('video', **params)

And seem to get no results (if I make 'rows': 10 then I get 10 results) - but in either case I seem to get no facets.

Any ideas how to get around this? After I figure this out I also wish to use the StatsComponent feature (e.g. &stats=true&stats.field=q_visits)

Thanks in advance

According to the facet examples in the pysolr client tests, you need to set the value for facet parameter to 'on'. Like below:

solr = pysolr.Solr('http://localhost:8983/solr/', timeout=10)`

params = {
  'facet': 'on',
  'facet.field': 'q_date',
  'rows': '0',
}

results = solr.search('video', **params)
