bq: My question is for indexed=false, stored=true field..what is optimized way
to get unique values in such field.
There isn't any. To do this you'll have to read the doc from disk,
it'll be decompressed
along the way and then the field is read. Note that this happens
automatically when
you call doc.getFieldValue or similar.
At the stored="true" level, you're always talking about complete documents.
indexed="true" is about putting the field data into efficient-access structures.
They're completely different beasts.
your original question was:
"Please guide me how i can tell solr not to tokenize stored field to decide
unique groups.."
Simply declare the field type you care about as a "string" type in
schema.xml. The use a <copyFeld> directive to copy the data to the
new type, and group on the new field.
There are examples in the schema.xml of string types and copyFields that
should help.
Best,
Erick
