How to refresh after updating synonyms.txt?

[Bashar3A]

Hi,

I want to understand how the process works. When I update the
synonyms.txt, how do I refresh and tell Sunspot to use the new
synonyms? Does it happen with next index, or restart?

One way I know will work is restarting Solr.

There might be a programmatic way to tell Solr to reload its config ..
or possibly a SIGHUP, but I don't know that for sure.

Thanks. I was hoping to avoid the restart, but at least I know now

Yeah, the Solr restart is necessary. You'll probably also want to reindex as well.

Synonym transformation can take effect both at query time and at index time. So depending on the nature of your synonyms (expansion, simple transformation) you may create some odd cases that affect relevancy or get incorrect results until you reindex.

Thanks Nick. I'll do that then.

Just stumbled on this thread while googling for something related.
Figured it's not too late to chime in.

To avoid the restart you could configure Solr multi-core [1]. Then you
can simply do a core RELOAD to refresh the synonyms. Much easier to
automate and avoids the downtime.

Thanks Jay. Will need to look into it.
