Updated labels on attached documents but now labelText: "labelname" does not work

[Siraj Mahal]

Within the attachment macro, I updated labels on documents (for ex. "main" (which is the old label to "business" (which is the new label)). For some reason when I use labelText: business (want to search only this specific page; using the page tree search macro) I now get 0 search results and none of the documents with the new label "business" are returned. However, when I search by the old label (labelText:main) all the documents all returned although they have the new updated label "business". Have already tried to re-add attachment macros/documents and reindexing manually did not work. 

Any way to fix this issue?
