(30142, 29893, 29010)<br><br>* Not all searches use those mappings, eg auth_finder.pl uses hardcoded <br> MARC fields<br><br>* ElasticSearch interprets lowercase boolean ops as literal search <br> terms. So "foo or bar" finds docs that contain "foo" and "or" and <br> "bar", but "foo OR bar" finds docs containing either "foo" or "bar".<br> AFAIK in 20.11 most of these problems are fixed, but see 30153 for a <br> rather recent fix (which I think is already available in the most <br> recent point releases)<br><br>* One thing that proved problematic during our initial migration of 500k <br> records was that ElasticSearch indexing is automatically triggered <br> after each edit for each item. This is fine when editing / catalouging <br> by hand, because all changes are immediatly available. But during <br> migration it caused a huge performance hit. There is / was some work <br> to offload the indexing to a worker process, but I think that's not <br> done / stalled. So we hacked our instance to skip the immediate <br> indexing via an ENV var (much easier than passing a command line flag <br> from the script through several layers of modules)<br><br>having said that, I think going with ES is a very smart move, because <br>(other then Zebra) it's a standard tool with very good docs and a lot of <br>knowledgable people (i.e. stackoverflow) to help you :-)<br><br>Greetings,<br>domm<br><br>-- <br>#!/usr/bin/perl https://domm.plix.at<br>for(ref bless{},just'another'perl'hacker){s-:+-$"-g&&print$_.$/}<br><br><br>------------------------------<br><br>Message: 3<br>Date: Fri, 1 Apr 2022 15:07:48 +1300<br>From: Mason James <mtj@kohaaloha.com><br>To: "koha@lists.katipo.co.nz" <koha@lists.katipo.co.nz>, Koha Devel<br> <koha-devel@lists.koha-community.org><br>Subject: [Koha-devel] Koha releases are available đ<br>Message-ID: <25b5b960-b3a0-34b4-d0ee-597f1f4bc7c0@kohaaloha.com><br>Content-Type: text/plain; charset=UTF-8; format=flowed<br><br>kia ora community,<br><br>the latest Koha packages are available<br><br>installation guide is below...<br> https://wiki.koha-community.org/wiki/Koha_on_Debian<br><br><br>cheers, Mason<br><br><br>------------------------------<br><br>Subject: Digest Footer<br><br>_______________________________________________<br>Koha-devel mailing list<br>Koha-devel@lists.koha-community.org<br>https://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-devel<br>website : https://www.koha-community.org/<br>git : https://git.koha-community.org/<br>bugs : https://bugs.koha-community.org/<br><br><br>------------------------------<br><br>End of Koha-devel Digest, Vol 197, Issue 1<br>******************************************<br></div><br><br>NOTE: You are receiving this mail because, the Requester/Technician wanted you to get notified on this request creation.<br></body></html>
