[Solr Wiki] Update of "TextProfileSignature" by EustacheFelenc

[Apache Wiki <wi...@apache.org>]

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "TextProfileSignature" page has been changed by EustacheFelenc:
http://wiki.apache.org/solr/TextProfileSignature?action=diff&rev1=4&rev2=5

  
  TextProfileSignature operates on raw text, without the filtering provided by Analyzers, and hence will fail to ignore HTML, normalize for diacritics, word stem/semantics, or incorporate the relative importance of different tokens, etc. It also considers only the bag of words, ignoring any word order.

+   <!-- An example dedup update processor that creates the "id" field on the fly
+        based on the hash code of some other fields.  This example has overwriteDupes
+        set to false since we are using the id field as the signatureField and Solr
+        will maintain uniqueness based on that anyway. -->
