Dear all, I have started to learn Solr for two months. At least right now, my system runs good in a Solr cluster.
I have a question when implementing one feature in my system. When retrieving documents by keyword, I believe Solr is faster than relational database. However, if doing the following operations, I guess the performance must be lower. Is it right? What I am trying to do is listed as follows. 1) All of the documents in Solr have one field which is used to differentiate them; different categories have different value in such a field, e.g., Group; the documents are classified as "news", "sports", "entertainment" and so on. 2) Retrieve all of them documents by the field, Group. 3) Besides the field of Group, another field called CreatedTime is also existed. I will filter the documents retrieved by Group according to the value of CreatedTime. The filtered documents are the final results I need. I guess the operation performance is lower than relational database, right? Could you please give me an explanation to that? Best regards, Li Bing
