Is the Solrj 6.4.x client backwards compatible with Solr 5.2.x?

can I use the latest Solrj client 6.4.x to query a 5.2.x solr cloud cluster?

Thanks

Solution

  • From the SolrJ/Solr cross-version compatibility

    SolrJ generally maintains backwards compatibility, so you can use a newer SolrJ with an older Solr, or an older SolrJ with a newer Solr.

    Disclaimer: this clarification does not apply to your question, but I want to add it for sake of completeness.

    A big leap was done passing from versions 4.x to versions 5.x and earlier and SolrJ clients were completely redesigned.

    So it is not possible use a recent version of SolrJ (5.x and earlier) with a SolrCloud (not Solr standalone) versions 4.x and older.
