: We added the following 2 fields to the above schema as follows: : : <field name="date" type="date" indexed="true" stored="true" required="true"/> : <field name="hlb" type="string" indexed="true" stored="true" : multiValued="true"/> : : where the "hlb" field consists of not more than 3-4 strings such as "Social : Sicence"/ : : Our 500,000 document index size increased to 166G! This seems completely
if you don't need fieldNorms for these fields (it almost never makes sense for dates and based on your description of hlb i doesn't sound like you'd need it there either) make sure that's disabled (you might already be doing that in the fieldType declarations, but i'm not sure) another way to reduce the amount of space (and improve date range query speed) is to reduce the granulatiry of hte dates you index (ie: round off to the nearest second, minute, hour, or day) so the number of unique terms in the field is reduced. -Hoss
