USE 455 - Skip libguides sub-pages that are root page#271
Merged
Conversation
Why these changes are being introduced: It was discovered that we had duplicates in LibGuides since adding sub-pages. This was because for guides that have sub-pages, the sub-page with "position = 1" is effectively the root guide, just by a non-friendly URL. How this addresses that need: We can quite easily skip these guides by detecting "position = 1" and "name = 'Home'" when analyzing the sub-page metadata from the LibGuides API. Side effects of this change: * Reduce duplication Relevant ticket(s): * https://mitlibraries.atlassian.net/browse/USE-455

Purpose and background context
Why these changes are being introduced:
It was discovered that we had duplicates in LibGuides since adding sub-pages. This was because for guides that have sub-pages, the sub-page with
position = 1is effectively the root guide, just by a non-friendly URL.How this addresses that need:
We can quite easily skip these guides by detecting
position = 1andname = 'Home'when analyzing the sub-page metadata from the LibGuides API.In addition, just a bit of cleanup of regex expressions and converting an INFO --> DEBUG logging statement.
How can a reviewer manually see the effects of these changes?
Compare the previous
v2tab against the currentv3tab from this spreadsheet: https://docs.google.com/spreadsheets/d/1G0ci9V-SMvqGuT3p0xwI6u63Hr1VTy2e-cLOu60LfAk/edit?gid=1391449591#gid=1391449591.While the total number of rows has increased, this is due to an expanded crawl scope for an unrelated issue.
What's important to note is the dramatic reduction, nearly to zero, for duplicated
titlecolumn values (a good indicator of a true duplicate).A couple of examples that are now de-duped:
Includes new or updated dependencies?
NO
Changes expectations for external applications?
