Is it possible to apply synonyms at query time? Or any other method to avoid reindexing the whole data again with change in synonym definitions ? for myuse case, typical synonyms looks like camelcase =\> CamelCase GAPS, gaps =\> Gaps Barca =\> Barcelona Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

yes you can have a query time analyzer in your mapping "search\_analyzer" which can be changed without reindexing. you can just use synonyms as query time instead of index time. simon On Tuesday, August 20, 2013 10:39:03 AM UTC+2, kul wrote: > Is it possible to apply synonyms at query time?

Very nice! Thanks Simon. Also, I looked around but could not find anything on how to make the change to synonym file take effect? For small no. of records i can see that it takes effect immediately after restart of es server, But for large no. of records i do not see synonym being applied even after restart.

If you are using synonyms at query time, any changes to the synonym file should take into effect after a restart. Can you share your analyzer configuration? -- Ivan On Wed, Aug 21, 2013 at 3:21 AM, kul [kuldeep.bora@gmail.com](mailto:kuldeep.bora@gmail.com) wrote: > Very nice! > > Thanks Simon. > > Also, I looked around but could not find anything on how to make the > change to synonym file take effect? > For small no. of records i can see that it takes effect immediately after > restart of es server, > But for large no. of records i do not see synonym being applied even after > restart. > > Thanks > > On Tuesday, August 20, 2013 9:01:08 PM UTC+5:30, simonw wrote: > > > yes you can have a query time analyzer in your mapping "search\_analyzer" > > which can be changed without reindexing. you can just use synonyms as query > > time instead of index time. > > > > simon > > > > On Tuesday, August 20, 2013 10:39:03 AM UTC+2, kul wrote: > > > > > Is it possible to apply synonyms at query time?

I'm wondering if you really need synonyms like "camelcase =\> CamelCase", and "GAPS, gaps =\> Gaps"? Just using a lowercase filter will give you hits on these documents. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
