Solr's Grouping feature is not working for one of our datasets. It yields the grouping field's value as *null* at times, randomly (we haven't established a pattern so far), and puts documents in a single bucket while the field's value is different for each doc. Filtering on the actual value of that field is working fine, though.
Our schema on this particular field is the same for the last three months, and data ingested just last week is impacted by this issue. With queries, we're able to filter out the documents with that field's values but they end up in the null group value and pollute the results.1 [image: Screenshot 2022-12-22 at 12.36.35 PM (1).png] -- Neeraj -- <https://www.youtube.com/watch?v=HfPkq3zW-X0> Shop at Local Stores 10 Million+ Users | 50+ Cities Android <https://play.google.com/store/apps/details?id=com.magicpin.local> | iOS <https://itunes.apple.com/in/app/magicpin-cashback-deals/id1171775851?mt=8> | Web <https://magicpin.in>
