Hi, wanted to make sure I'm implementing sort in an efficient way... I need to allow users to sort by documents' title field. A title can contain 1-20 words. Title examples: "new project meeting minutes - Oct 2015 - new chance on the horizon" or "how to create a wonderful presentation".
I'm already indexing title as a TextField, and I not comfortable with indexing it again as an extra StrField field I'll need plus the extra FieldCache memory. I can probably avoid the FieldCache by using docValues to reduce mem usage. *But... is there a more efficient way to provide this sort? perhaps something that takes advantage of title field is a chain of words with whitespaces between words?* My index is 100's of millions of documents over 8 shards. Thanks.
