Solr多值字段获取索引

Question

I have two multivalued solr fields. Is it possible to get the index of one value in one field and use that index to get the value of another field.

For example: Field1: [A,B,C] Field2:[2010,2011,2012]

I want to know what letter is in 2012.

Answer 1

yes, if you have those fields stored, then, you are guaranteed its values will be returned in the same order they were inserted. So you can retrieve both fields, look at what position is 2012 in Field2, then look at that position in Field1.
