I am unclear on how does searching work while indexing. lets say I already have a document indexed (version 1), and I updated the document, so I will index it again (version 2), what happens when the user is searching while indexing version 2? Will the user get results from version 1? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Well, good grief, the answer to the poster's original question is PERHAPS (not yes!). It depends on the timing between the search request and the (asynchronous) indexing. There is a short (but finite) amount of time after the update request that a search will still return the previous version. At some point in time (this is the eventually part) that window will close and the updated, just indexed document will be returned. Also, if the search request happened before the indexing and the client is pulling results back using scrolling or scanning then he definitely will not see the update, I think.
