: I want to index a field with an array of arrays, is that possible in Solr?
Not out of the box ... you can implement custom FieldTypes that store any data you want in using a byte[] but you'd still need to do some tricks with your FieldType to get the ResponsWriter to write it out in a meaningful way. the simplest appraoch would be to just encode the multiple values into a String in some way (comma seperated, or something) -Hoss
