Hi Jinal, The overhead is marginal. ES initially constructs a filter based on the incoming types and uses that while searching. The result of that fitler iis also cached, so repetitive usage has even less overhead.
Note though that you will be search more data, so underlying query may take longer simple by having to analyze more documents. However, roughly speaking, querying one type with 1M docs is roughly identical to querying 10 types with 100K docs each.
