: I see this interesting line in the wiki page LargeIndexes
: http://wiki.apache.org/solr/LargeIndexes (sorting section towards the
: bottom)
:
: Using _val:ord(field) as a search term will sort the results without
: incurring the memory cost.
:
: I'd like to know what this means, but I'm having a bit of trouble
: parsing it.... What is _val:ord(field) exactly? Does this just mean
that's refering to using function queries with the "_val_" hack that is
supported by the LuceneQParserPlugin...
http://wiki.apache.org/solr/SolrQuerySyntax
...it *seems* to be suggesting that if you use a function query based on
the ordinal value of a field, you won't need the same amount of memory as
if you just sorted on that field ... but that is incorrect, so i removed
that like from the page. (for string fields, the same FieldCache is
initialized either way, for non string fields following that advice could
result in 2 or 3 times as much memory being needed for both the numeric
FieldCache and the String FieldCache entries)
