Infinite Loop with See Also Reference

[Tim Spindler]

You can see this with concerto data. Search "People with disabilities Recreation" and it gives you

People with disabilities -- Recreation ;

    See Also From Tracing -- Topical Term People with disabilities Recreation (2)

The See Also link is self referential so it keeps looping back and never taking you out to an actual search.

Here is the HTML to see the linking

People with disabilities -- Recreation

I just found this https://bugs.launchpad.net/evergreen/+bug/1271198 which may be the same issue as I highlight above.

It's actually a different issue where the browse parameters are sticking when you launch a separate subject or author search from the bib record or search results page.

I can confirm that the same thing is happening in PINES:

We've seen the infinite loop issue with both author and browse entries.

For the author entries, the code that will be added to bug 1638299. I'll mark this bug as a duplicate of that one.

For the subject entries, I believe I traced this down to a local configuration issue where sites have chosen to enable the All Subjects index for browse instead of enabling the specific topic, name, geographic, temporal indexes for browse. This local configuration choice was typically made so that the subject browse would display the entire subject string instead of individual components of the string.

With the addition of the code from bug 1662541, sites will no longer need to make this configuration choice for most subject indexes, with the exception of the name index. I have confirmed with a small dataset that with the code from bug 1662541, we are able to display the entire string without adding those duplicate entries identified in this bug.
