Apache Solr 8 behaviour when ZK data is deleted
My Question is related to Apache Solr 8. If the zookeeper is wiped out of it's data, it looks like the Solr also deleted all the indexes. I wanted to know if is normal that if the configsets related to a collection are not inside zookeeper, then its Solr indexes are deleted from the file system? Because in the previous versions, the collections were not visible on the Solr console, but the index on file system was not deleted. Is it something added as a new feature in Apache Solr 8.0? I could not find anything in the Release Notes.

Re: Sort on PointFieldType
Thanks for the answers. I am using Solr version *6.4.2*. I got your answers. I have another question. Can we use a *Range query* on point field? I am trying to do something like *fq=abc.pqr_d:[ 1500 TO 2000 ]* Is it a valid filter?

Sort on PointFieldType
Hi, I have a *field* that is of *PointType *and I tried to sort on that field. But looks like sorting does not work on PointType. Or am I doing something wrong?

Re: Solr query particular value of a field last
Basically, you need to boost some documents low. For this, you can either use solr’s Boost Query ( bq ) or Boost Function (bf) parameter. For example in your case:- If you want the documents with countries A and B to show last in the result, you can use:- bq=( country:A OR country:B )^-1 Note that a negative boosting has been done here. I would say this approach is better than sorting because other documents maintain their actual order and only those documents are boosted up or down, which satisfy the condition.
