When the search uses parameters prefix:, intitle: or +incategory:, it should not propose to create the page. See link, new users have been confused by this when searching archives and created pages like <something> prefix:Talk:Main Page . It seems unlikely that pages containing any of those strings need to be created.
These are legitimate page title names, no need for the software to block them.
If a local wiki doesn't want them, an AbuseFilter or entry to the page title blacklist are more appropriate. Marking WONTFIX.
Where they're syntactical elements of a search query they really should be excluded from the search suggestion.

This also happens with the ~ and - prefixes, and the * suffix.
MediaWiki:Searchmenu-new is also a bit ugly: '''Create the page "[[:$1]]" on this wiki!''' I understand the bold, but the exclamation mark? While at it, if this bug is fixed the message can be made a bit more encouraging, like «'''You can create the page "[[:$1]]" on this wiki.'''» (such a wording would currently make the effects of this bug worse); the bug 27311 could make the link more helpful and always valid whatever the permissions/processes on the wiki.
As mentioned on bug 29989, this is also the case with double quotes used in search phrases.

We actually did this with Cirrus. If other backends support fancy syntax and want to do the same, they can too by returning true in SearchResultSet::searchContainedSyntax() implementations.
