Our backlinks feature is flawed.
There are several problems
- If you have a topic called "Hello++Hello" the search code barfs because of the + signs in a regex.
- If the topic name you search for is part of an I18N word like SuperDuperØsters then it finds SuperDuper as a backlink because it does not see the Ø as a letter. Same with accented characters.
There are two problems.
First the regex search cannot handle regex characters. We need to escape the regex characters of %TOPIC. Maybe we need a BACKLINKS macro which can be defined only in template land where we can escape the regex characters in TOPIC?
2nd the regex in the backlinks templates has a [A-Za-z0-9] in them.
We cannot use A-Z in ANY regex in our user interface. Most countries in this world has other characters then A-Z.
Even if we cannot get it perfect, we can at least make it near perfect. We probably have to use a character class. Maybe a negative one that lists all the characters we do not see as part of a topic name. We are depending on the name filter and I am not sure we can get to this. But at least we can use the default. Not many admins will ever change the namefilter anyway.
