Hi, Trying to understand the Index Warmup issue. Is a warmer specific for a search word and actually puts that word in the cache? So it means that I need to know in advance the search words that take a long time and put their text in a specific warmer for each search text?

The most useful thing to do with warmups is to load fielddata into memory. eg if you sort or facet on a field, or use geopoints, then create a warmup query that does something similar. Also, if you have regularly used static filters (eg "status" == "active), then run those - they will be cached. clint -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
