>          Issue Type: Bug
>    Affects Versions: ManifoldCF 1.7, ManifoldCF 1.8
>            Reporter: Aeham Abushwashi
>            Assignee: Karl Wright

>
> After upgrading to mcf 1.7 or later, pre-existing documents are recrawled and re-indexed even if they have not changed in any way since their last pre-upgrade crawl. The impact can be significant for large manifold deployments with millions+ static documents.
> There appear to be three contributing factors:
> 1. The empty transformation version of a legacy document is different from the initial value of "0+0!" - in PipelineObjectWithVersions#buildAddPipeline and IncrementalIngester#checkFetchDocument
> 2. Incorrect comparison of output versions in PipelineObjectWithVersions#buildAddPipeline where oldOutputVersion is compared to a VersionContext object instead of the version string, which can be obtained by calling VersionContext#getVersionString - if IPipelineSpecification#getStageDescriptionString continues to return a VersionContext object, a rename of the method could be useful
> 3. In PipelineObjectWithVersions#buildAddPipeline, a null value for newAuthorityNameString is not treated the same as an empty string (like it is in other methods)
