While migrating from Solr legacy faceting to Solr streaming API, how to
implement the below parameters:
&facet = true
&facet.range = {!key=age_ranges}age
&f.age.facet.range.start = 0
&f.age.facet.range.end = 100
&f.age.facet.range.gap = 10
&facet.range = {!key=price_ranges}price
&f.price.facet.range.start = 0
&f.price.facet.range.end = 1000
&f.price.facet.range.gap = 50
&facet.field = a_field
&facet.minCount = 1
How can I implement these parameters using the new facet streaming with
parallel functions. I understand rollup() functionality has to be used.But
the documentation is limited and I am not able to understand the underlying
functionality. Can someone help me with this?
Ref Sample Query being currently used:
q=(score:[*+TO+*])+AND+(field:378/content)+AND+(crawl_date:[2015-01-01T18:30:00.000Z+TO+2017-02-01T18:30:00.000Z])
&facet.range=score&facet.range=project_score&facet.range=publish_date&f.score.facet.range.start=0
&f.score.facet.range.end=1000&f.score.facet.range.gap=10&facet=true&f.project_score.facet.range.start=0.0
&f.project_score.facet.range.end=1.0&f.project_score.facet.range.gap=0.01&f.publish_date.facet.range.start=1970-01-01T00:00:00Z
&f.publish_date.facet.range.end=2017-02-01T14:09:26.763Z&f.publish_date.facet.range.gap=%2B1MONTH&rows=0&facet.field=project_score
&facet.field={!key%3D378+facet.prefix%3D378/content}field&facet.field=Tags&facet.field=patent_publication
&facet.field=score&facet.limit=1000&facet.mincount=1
