Re,
I don't think there's a risk, but you may want
to add
"contains:delete",
"contains:edit", "contains:inline" &
"contains:?editor=" to your list...
At worse it will make indexing faster.
I understand the ?editor= pattern.
I'm concerned that first three might wildcard exclude too much.
Can you provide additional guidance on the url pattern so that a page
called "delete%20an%object" is not included, for example?
delete, edit & inline are usually used in urls such as
"xwiki/bin/delete/SpaceName/PageName", so you could use "contains:
bin/edit"
bin/delete , bin/inline , bin/objectremove and so on...
If using the "/" sign doesn't break the googlesearch syntax it should work
fine.
