Admin Optimize

[Rick Leir <ri...@canadiana.ca>]

Hi all,
The Solr Admin new UI in 5.4 lost the Optimise button in core admin. What
did it do, and is the 'Optimize' more automatic? Google is not helping me,
but then perhaps I should go past the first results page!

It is in the screendump here:
https://cwiki.apache.org/confluence/display/solr/Core+Admin

no mention of it here:
https://cwiki.apache.org/confluence/display/solr/CoreAdmin+API

Thanks
Rick

I looked and it's the new UI. Usually only visible on the "core admin"
tab and it's not there in either Cloud mode or stand-alone.

definitely visible on the old UI.

I did not deliberately remove that button, so if it is missing, it could
be a bug. Is it missing on the old, or new, or both UIs?

Thanks!

Right, the whole optimize thing is in a bit of a state of flux. For
indexes that change quite regularly, it's something of a trap as
making one big segment gets in the way of the merging algorithm. It'll
still work, but it's not all that useful.

For static indexes there's anecdotal evidence that it is useful, in
fact I know one of the devs is trying to quantify it now.

Having an optimize button right there on core admin encourages people
to press it, who _wouldn't_ want an optimized index? ;)

All that said, I'm not sure this is intentional or not, thanks  for
bringing it up. If you must optimize, you can still do it by entering
this URL:

http://solr_server:port/solr/core_or_collection_name/update?optimize=true

We'll have to do something to reconcile the page in the admin guide
though if we leave the optimize button off.

Best,
Erick
