Can files be faceted based on their size ?

[neuron005 <ne...@gmail.com>]

*Can fileSize be faceted? *I tried to facet them, but fileSize is of type
string and can not be faceted.
I want to facet my doc and pdf files according to their size. I can
calculate file Size but they are of type string.
What should I do in order to achieve that?
Thanks in advance

Well, you can try adding a <copyField>  directive to put it into
a numeric field....

But you need to provide significantly more details. From what
you've said there's not enough information to say much besides
"it should work".

Perhaps you should review:

Thanks for replying
I tried using "Trie" types for faceting solr but that did not solve the
problem. If I use Trie types(for e.g. I used tlong)...it shows "schema
mismatch error" as in FileListEntityProcessor api , fileSize has been
defined of type string. That means we can not apply facet.range on fileSize.
Am I right? 
Thanks

Well, I wouldn't store it as a string in the first place. Otherwise,
you're right,
you have to store it as an entity that compares lexicographically, usually by
left-padding with zeroes.

But don't do that if at all possible, it's much more expensive than
storing ints or
longs, so can you re-index these as one of the Trie* types?

But sir
fileSize is of type string, how will it compare?

Since you want to apply range faceting you need to use trie based types.
