You add multiple fields with the same name to a document, say keywords. <doc> <field name=keywords>solr<field/> <field name=keywords>lucene<field/> <field name=keywords>seach<field/> </doc> If have configured the the field keyword in the index to be multivalued, then solr will dump the values of each field in your document into the field keywords. When you request that solr return the value in the field keywords, then you get a coma seperated list of the keywords.

You cannot remove a field from a document, documents are read only, you have to reindex the document with the same unique id and the new information. > Based on > http://wiki.apache.org/solr/FieldOptionsByUseCase, it says to use > it to "add multiple values, maintaining order " Is the order for > indexing/searching or for storing/returning? Not sure, but I would assume that the values are stored in the field in the order that the fields are specified in the document. Brian
