Compute and cache the DocSet that matches a query. The normal usage is expected to be cacheDocSet(myQuery, null,false) meaning that Solr will determine if the Query warrants caching, and if so, will compute the DocSet that matches the Query and cache it. If the answer to the query is already cached, nothing further will be done.

If the optionalAnswer DocSet is provided, it should *not* be modified after this call.

Parameters:

query - the lucene query that will act as the key

optionalAnswer - the DocSet to be cached - if null, it will be computed.

mustCache - if true, a best effort will be made to cache this entry. if false, heuristics may be used to determine if it should be cached.

Parameters:

query -

filter - may be null

lsort - criteria by which to sort (if null, query relevance is used)

offset - offset into the list of documents to return

len - maximum number of documents to return

flags - user supplied flags for the result set

Returns:

DocListAndSet meeting the specified criteria, should not be modified by the caller.

Throws:

java.io.IOException
