Subject [jira] [Updated] (CLEREZZA-678) Extend GraphIndexer interface to support pagination
Date Fri, 27 Jan 2012 18:34:17 GMT

     [ https://issues.apache.org/jira/browse/CLEREZZA-678?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Daniel Spicar updated CLEREZZA-678:
-----------------------------------

    Description: 
the findResources methods should support pagination by extending the interface with (from,
to) arguments. From is inclusive, to is exclusive.

Background: Currently the idea of the maxhits parameter in GraphIndexer has been misunderstood.
It can be used to support pagination in this manner:
First get results from 0-20 with maxhits 20. Then the user wants to see results from 20-40,
so the same IndexSearcher can be used with maxhits set to 40. Because the IndexSearcher already
holds results 0-19 in memory, only results 20-39 are loaded from the index.
