Alternate email is rickleir at yahoo dot com Thanks, but I don't really think a general copy-field is what I want. I want to specifically search for particular values in named fields. For example: if the document has a "field1" then use "field1:[1 TO 100]"; but if there is no "field1", then check if there is a "field2"; if there is a "field2" then use "field2:[1 TO 100]; but if there is no "field2", then use "field3:[1 TO 100]. Something like: ?q=*:*&fq=if(exists(field1),field1:[1 TO 100],if(exists(field2),field2:[1 TO 100], field3:[1 TO 100])) But is this does not work. Is it even possible? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
