Math books sorting incorrectly in collection

[josieg]

Describe the bug
When I open the Adult Basic Education > Math category, there are a whole bunch of books listed that shouldn't be appearing there.

I checked a few of the books that are displaying incorrectly here (such as Brief Calculus and Business Math: A Step-by-Step Handbook, and all of those books have the correct categories selected in SOLR.)

To Reproduce
Steps to reproduce the behaviour:

1. Go to the Open Textbook Collection.
2. In the left subjects menu, click "Adult Basic Education" and then "Math"
3. The collection will display 101 results (there should be less than 5)

Same thing also seems to be happening to the Business > Entrepreneurship category

Summary of investigation and conversation so far with @josieg:

• Checked the back-end for any issues with taxonomy, no issues found
• Checked individual books to ensure they are not in the wrong taxonomy, no issues found

Next steps:
Figure out what is unique about the 101 results that appear in the ABE "Math" category, and if there's a bug with the logic generating the menu.

I just noticed that if you just type in "Math" into the collection search, you get the same 101 books.

Hi Josie, this appears to be resolved. Can you please confirm?

[josieg]

Yep, can confirm...

Hi Alex, this is happening again but with different categories.

See Social Sciences > Sociology (https://open.bccampus.ca/browse-our-collection/find-open-textbooks/?subject=Sociology)

Also, there is a Physics subcategory showing under Education?

@josieg Very interesting, I will look into this further. Can you think of anything that has changed recently. For example, any new characters or changes we made to categories? I will try to confirm if we're getting duplicates back from Equella, or if it's how we're parsing the data that's causing the issue.

FYI the Sociology category is displaying the correct books again. But Physics is still showing up under "Education."

These are all of the changes we've requested be made to the collection categories in 2020.

They include adding the following new sub categories:

• Computer Science > Computer Science - General
• Earth and Ocean Sciences > Ocean Studies
• Adult Basic Education > Science

And we also put in a request to change the "Creative Non-Fiction" sub-category to "Creative Writing"

Thanks @josieg I've resolved the Physics menu item showing up in the incorrect category. Glad to hear the Sociology category is displaying the correct books again. I'm not entirely sure why this happened.

Krista noticed the same error with ABE->Math. Captured here:

@josieg , how many results should come back in the Chemistry category? I'm currently seeing 61.

[josieg]

It's showing me 7 now, which should be correct.
