Hey Albert, Just to remind you, that the fields in Lucene are per document and not per index. This means that you can have documents in an index which have different fields altogether. So, in effect, you can all your document types to your existing index. And guess what, you don't need to change anything for this.
All the best.

Document 2 code, title, content, type, language, date, ... ... Document n code, title, content, type, language, date, ... Now all document types share the same fields, but in a future we need to add more document types with specific fields. I allways sort documents by date. I have 200.000 new documents each day and 130 million documents. The janaury index size is 4.2Gb (the data size is about 10Gb). I was wondering how to index the new document types. Option 1: One index for each document type. Each index will have its fields. Problem: I will have to perfom a search for each index, and sort results by date. Option 2: One big index containing all fields. A field could be empty if the field is not applicable for that document type. Option 3: One big index containing all common fields, and adding and extra field named metadata. Inside this field I will add all specific fields (field1:value1 field2:value2). Comments, pros and contras will be appreciated. I don't know exactly the diference between option 2 and option 3.
