Subject Re: Documents that didn't change are reindexed

Hi Gustavo,

I take it from your question that you are using the Web Connector?

All connectors create a version string that is used to determine whether
content needs to be reindexed or not.  The Web Connector's version string
uses a checksum of the page contents; we found the "last modified" header
to be unreliable, if I recall correctly.
