I'm not sure if grouping is the right feature to use for your requirements... Grouping does have an impact on performance which you need to take into account. Depending on what grouping features you're going to use (grouped facets, ngroups), grouping performs well on large indices if you use filters queries well. (E.g. 100M travel offers, but during searching only interrested in in travel offers to specific destinations or in a specific period of time). Best way to find this out, is to just try it out.
