Summon will be unavailable from 10 am Wednesday morning, for about one hour. The underlying index is being modified and re-built to introduce new features. One of those new features is a change so that this sort of outage, their first, should also be their last, as future changes should be done on the fly.

A note from Serials Solutions:

With this new re-index, we will be merging matched documents to improve the metadata and full text indexing as well as eliminating duplication. In addition, you will notice several bug fixes and improvements with search capabilities. Some of these will be improvements relating to: proper diactric handling, improvements to Japanese language searching, and many more performance and scalability improvements.
