But here the "signature" field has field type "string". when you index it, you put the whole string somewhere and give it an id, for example, 323454. In a doc, you only need to reference this id 323454 if the doc happens to contain the same signature value. Now suppose I have a lot of docs with same signature and signature is a very long string. It seems to me indexing the signature will save me hard disk space. In short, what I mean is that if you index a "string" field, you can retrieve it without loss. So you don't need to store it separately. what do you think? -- View this message in context: http://www.nabble.com/which-one-will-save-hard-disk-space--tf3469131.html#a9682449 Sent from the Solr - User mailing list archive at Nabble.com.
