Honestly there are many ways you could solve this ... I would create /accounts/search/less_than/10000 /accounts/search/greater_than/10000 /accounts/search/between/10000/20000
And then you could either have a generalised Serach restlet ... or you could have restlets handling each search case individually ... I would have a search class that actually does the heavylifting of seaching balances.. and restlets that support that class because they understand the URLs .. I hope I was clear enough Cheers Piyush
