Could anybody tell us some internals about "Too many values for UnInvertedField faceting on field xxx" ?
We have two solr servers. Solr A : 128G RAM, 60M docs, 2600 different terms with field “code”, every term of field “code” has fixed length 6. the sum count of token of field “code” is 9 Billions. The total space used by field “code” is 50 Billions. Solr B: 128G RAM, 140M docs,1600 different terms with field “code” every term of field “code” has fixed length 6. the sum count of token of field “code” is 18 Billions The total space of field “code” is 90 Billions. When we do facet query “ q=*:*&wt=xml&indent=true&facet=true&facet.field=code” Solr B is OK, BUT Solr A meets Exception with the message “Too many values for UnInvertedField faceting on field code”. Now we think the limitation of UnInvertedField is related with the number of different terms with one field Could anybody tell us some internals about this problem? We won’t to use facet.method=enum because it ‘s too slow to use. Thanks!
