<div class="moz-cite-prefix">Hi Balz<br>
<br>
Thanks very much for your feedback!<br>
<br>
I just found an alternative Elasticsearch client, which has no
Lucene dependencies<br>
<br>

<br>
but I think we should upgrade Lucene anyway and your suggestions
below make a lot of sense!<br>
<br>
Thanks very much<br>

<div>I proposed the same thing in 2013:</div>

</div>
<div>It would be great to see Lucene 6 in yanel.</div>
<div><br>
</div>
<div>Regarding source code repository of yanel/yarep etc., here
my thought:</div>
<div>- I would create a new branch "lucene2.9.2" in all
repositories of the current latest status. This way, people
who want to work with this latest version and lucene 2.9.2 can
still get the code very easily.</div>
<div>- The master branch would then be upgraded to use Lucene 6.</div>
<div><br>
</div>
<div>Some other remarks:</div>
<div>- Lucene 6 runs on Java 1.8 or later. So make sure all old
dependencies are upgraded as well! (in all repositories like
yarep, security etc.)</div>
<div>- The index of 2.9.2 won't be compatible, Lucene only
guarantees compatibility within the same major release (e.g.
6.0.0 and 6.6.0 will have the same index format).</div>
<div><br>
</div>
<div>The upgrade must be done carefully, because I currently
don't see what libraries Lucene is depending on (e.g. Log4j,
apache commons stuff...), I assume that many libs currently in
yanel (which are out of date) will have to be upgraded as
well. Example: yanel uses log4j 2.0 beta8 ... Lucene 6 will
most probably not use a beta version :-) so an upgrade to
log4j 2.5 is most probably required.</div>

<br>
I have recently tried to integrate Elasticsearch into
Yanel, but have<br>
trouble doing this, because Elasticsearch requires a more
recent Lucene<br>
version than Yarep is using (2.9.2).<br>
<br>
<br>
Lucene already offers version 6.6.0<br>
(<a moz-do-not-send="true"
href="https://lucene.apache.org/core/downloads.html"
rel="noreferrer" target="_blank">https://lucene.apache.org/cor<wbr>e/downloads.html</a>)
and I think it would be<br>
good to upgrade Lucene finally. I am not sure whether
search indices are<br>
still compatible, but one could re-generate a search
index.<br>
<br>
What do you think? Any objections?<br>
<br>
Thanks<br>
