I am seeing some some odd behavior with range facets across multiple shards. When querying each node directly with distrib=false the facet returned matches what is expected. When doing the same query against the collection and it spans the two shards, the facet after and between buckets are wrong.
I can re-create a similar problem using the out of the box example scripts and data. I am running on Windows and tested both Solr 5.0.0 and 5.1.0. This is the steps to reproduce: c:\solr-5.1.0\solr -e cloud These are the selections I made: (specify 1-4 nodes) [2]: 2 Please enter the port for node1 [8983]: 8983 Please enter the port for node2 [7574]: 7574 Please provide a name for your new collection: [gettingstarted] gettingstarted How many shards would you like to split gettingstarted into? [2] 2 How many replicas per shard would you like to create? [2] 1 Please choose a configuration ... [data_driven_schema_configs] sample_techproducts_configs I then posted some of the sample XMLs: C:\solr-5.1.0\example\exampledocs> java -Dc=gettingstarted -jar post.jar vidcard.xml, hd.xml, ipod_other.xml, ipod_video.xml, mem.xml, monitor.xml, monitor2.xml,mp500.xml, sd500.xml This first query is against node1 with distrib=false: http://localhost:8983/solr/gettingstarted/select/?q=*:*&wt=json&indent=true&distrib=false&facet=true&facet.range=price&f.price.facet.range.start=0.00&f.price.facet.range.end=100.00&f.price.facet.range.gap=20&f.price.facet.range.other=all&defType=edismax&q.op=AND There are 7 Results (results ommited). "facet_ranges":{ "price":{ "counts":[ "0.0",1, "20.0",0, "40.0",0, "60.0",0, "80.0",1], "gap":20.0, "start":0.0, "end":100.0, "before":0, "after":5, "between":2}}, This second query is against node2 with distrib=false: http://localhost:7574/solr/gettingstarted/select/?q=*:*&wt=json&indent=true&distrib=false&facet=true&facet.range=price&f.price.facet.range.start=0.00&f.price.facet.range.end=100.00&f.price.facet.range.gap=20&f.price.facet.range.other=all&defType=edismax&q.op=AND 7 Results (one product does not have a price): "facet_ranges":{ "price":{ "counts":[ "0.0",1, "20.0",0, "40.0",0, "60.0",1, "80.0",0], "gap":20.0, "start":0.0, "end":100.0, "before":0, "after":4, "between":2}}, Finally querying the entire collection: http://localhost:7574/solr/gettingstarted/select/?q=*:*&wt=json&indent=true&facet=true&facet.range=price&f.price.facet.range.start=0.00&f.price.facet.range.end=100.00&f.price.facet.range.gap=20&f.price.facet.range.other=all&defType=edismax&q.op=AND 14 results (one without a price range): "facet_ranges":{ "price":{ "counts":[ "0.0",2, "20.0",0, "40.0",0, "60.0",1, "80.0",1], "gap":20.0, "start":0.0, "end":100.0, "before":0, "after":5, "between":2}}, Notice that both the "after" and the "between" are wrong here. The actual buckets do correctly represent the right values but I would expect "between" to be 5 and "after" to be 13. There appears to be a recently fixed issue (https://issues.apache.org/jira/browse/SOLR-6154) with range facet in distributed queries but it was related to buckets not always appearing with mincount=1 for the field. This looks like it is a different problem. Anyone have any suggestions or notice anythign wrong with my query parameters? I can open a Jira ticket but wanted to run it by the larger audience first to see if I am missing anything obvious. Thanks, Will
