I have written a piece of code, on top of reindex functionality provided by ElasticSearch.  
The code takes an alias name and searches for the linked index.  
Let's say alias name is x then index name is x\_v1.  
Later it creates index x\_v2 (with updated analyzer) and call reindex to index data from x\_v1 to x\_v2.  
Then it deletes x\_v1 after linking x\_v2 to alias x.

Now when I am checking the metadata of x\_v2, it has updated analyzer. But when I am actually querying the data it is searching according to the previous analyzer.

I am doing anything wrong?

Based on the description you've written here, I can't see what is wrong. Maybe add in your code (or link to it)? I do something similar to this in an open source project, without problem (doesn't use the reindex API, but the aliasing pattern is the same).
