<p>
Enables partial results to be returned if one or more index partitions are unavailable. When your search index is
partitioned across multiple search instances, by default Amazon CloudSearch only returns results if every
partition can be queried. This means that the failure of a single search instance can result in 5xx (internal
server) errors. When you enable partial results, Amazon CloudSearch returns whatever results are available and
includes the percentage of documents searched in the search results (percent-searched). This enables you to more
gracefully degrade your users' search experience. For example, rather than displaying no results, you could
display the partial results and a message indicating that the results might be incomplete due to a temporary
system outage.
