[Koha-devel] problem with Search::Elasticsearch-v7 and ES6

[Mason James]

yes, something like that :)


the best way forward could be for us to package our own version of Search::Elasticsearch v7 (either 7.30 or 7.715), with the following 2 modules included...

https://metacpan.org/release/EZIMUEL/Search-Elasticsearch-Client-6_0-7.30
https://metacpan.org/release/EZIMUEL/Search-Elasticsearch-Client-6_0-Async-7.30

this method is described as working below, and should allow koha to works with both ES6 and ES7 servers...

   Compatibility needs hacking to work (Client 7.3 ==> Server 6.8) #198
   https://github.com/elastic/elasticsearch-perl/issues/198



we will also need to explicitly set "client => '6_0::Direct'" when using ES6 (as the code defaults to 7_0::Direct)

probably by adding the following to koha-conf.xml...

     <elasticsearch>
          <client>6_0::Direct</client>
     </elasticsearch>
