Hi,

The way I understand the Shard Query Cache 
<http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.4/index-modules-shard-query-cache.html>,
 
it invalidates *ALL *cached results in a shard when the shard refreshes, 
given that *ANY *data in the shard has changed.

My data changes all the time, but I'd like to keep some of my query results 
cached for a while - say 1 minute.

My refresh interval (5 sec) cannot be changed because I need near-realtime 
searches for other query types.

I can read that there is a "indices.cache.query.expire" config setting 
where the general TTL of all Shard Query Caches can be set, but the docs 
specify that this shouldn't really be used because all cached results are 
invalidated anyway upon refresh.

Two questions:

1. Is my understanding of the Shard Query Cache invalidation mechanism 
correct?
2. Is there a way to specify a TTL on the query-level, that makes the 
cached result survive the refresh interval?

Thanks,
Lasse
