Solr 7.5.0, error sorting a “pdate” field in ascending 'asc' direction










1














by usign the Solr7.5.0 webUI, I am trying to sort a field of my schema "data_creazione", by setting:



&fl=data_creazione:[2017-11-12T00:00:00Z TO NOW]&sort=data_creazione asc



my complete query URL being:



http://localhost:8983/solr/NUR/select?fq=data_creazione:[2017-11-12T00:00:00Z%20%20TO%20%20NOW]&q=regione%20lazio&sort=data_creazione%20asc


When i inspect the results I am observing a strange and erroneous sorting behavior:



  • results from 0 to 9 (start=0,rows=10) are correctly ordered (from 2018-03-01 to 2018-03-02)

  • results from 10 to 19 (start=10,rows=10) are correctly ordered (from 2018-03-05 to 2018-03-07)

  • results from 20 to 29 (start=20,rows=10) are incorrectly ordered (from 2018-02-23 to 2018-03-1)

Moreover, I am trying to send the same query to Solr 7.5.0 from a .netcore2.1 application by using the Solr.net driver, and I am returned the same identical sort error.



NOTICE: when I try to query the same query but in DESCENDING 'desc' direction all things go fine. All results' pages are correctly ordered.
This error does not appear with Solr 7.2.0: ascending and descending sorting over date fields works fine



In my managed-schema the field "data_creazione" is declared this way:



<fieldType name="pdate" class="solr.DatePointField" docValues="true"/>
...
<field name="data_creazione" type="pdate" multiValued="false" indexed="false" stored="true"/>

  • Did you reindex (completely) after changing to the pdate type? Can you create a set of documents that can replicate this issue from scratch with an empty index?

  • All documents've been indexed after managed-schema updated. Also, I can provide U the set of documents that replicates the problem. Tell me how...
