Hey, Don't think so, but is it possible to reload the synonym list without restarting the cluster? The indices using this would need to be rebuilt for things to correctly take effect. Perhaps it would make more sense to add a new analyzer for the new synonym list and create a new index using that analyzer, rebuild the data into there and swap an alias? Along these lines, what API is used to dynamically add a new analyzer? Maybe I'm not looking in correct location, but I can't find any examples. Thanks! Paul ---

Hey, The only way to reload the synonym file is by closing and opening the index. Adding new analyzers requires similar mechanism, where you close the index, update its settings with the new analyzer, and then open it again. -shay.banon On Tue, Jul 26, 2011 at 11:25 PM, Paul [ppearcy@gmail.com](mailto:ppearcy@gmail.com) wrote: > Hey, > Don't think so, but is it possible to reload the synonym list > without restarting the cluster?

Ah, great to know, thanks! That will be very helpful. I did some digging and while I couldn't find anything in the docs, I managed to stumble across an example somebody had posted on how to dynamically an analyzer during index creation. For those interested, it looks like this: curl -XPUT '[http://localhost:9200/twitter/](http://localhost:9200/twitter/)' -d '{ "settings" : { "index" : { "number\_of\_shards" : 1, "number\_of\_replicas" : 1, "analysis":{ "analyzer":{ "really\_verbatim":{ "type":"custom", "tokenizer":"whitespace", "filter":[ "really\_verbatim\_filter" ] } }, "filter":{ "really\_verbatim\_filter":{ "type":"word\_delimiter", "generate\_word\_parts":"0", "generate\_number\_parts":"0", "catenate\_words":"0", "catenate\_numbers":"0", "catenate\_all":"0", "preserve\_original":"1", "split\_on\_case\_change":"0", "split\_on\_numerics":"0", "stem\_english\_possessive":"0" } } } } } }' On Jul 26, 10:41 pm, Shay Banon [shay.ba...@elasticsearch.com](mailto:shay.ba...@elasticsearch.com) wrote: > Hey, > > The only way to reload the synonym file is by closing and opening the > index.
