Case sensitivity inconsistent with 2-word titles in names/refs on Links REST API

[DovOps]

Unsure if this is a data problem or a code problem (Feels like the former) but certain case-sensitive links REST calls produce no results when the attempted ref is lowercase and the name contains 2 words (e.g. Bava Metzia, Moed Katan, etc) but does produce results when Title Case. Single word title refs work whether upper or lower.

• Example 1: Rosh Hashana 2a

• https://www.sefaria.org.il/api/links/rosh%20hashanah%202a (Empty)

• https://www.sefaria.org.il/api/links/Rosh%20hashanah%202a (Empty)

• https://www.sefaria.org.il/api/links/Rosh%20Hashanah%202a (Results)

• Example 2: Berachot 2a / Berakhot 2a / Berachos 2a. (All have results)

• https://www.sefaria.org.il/api/links/berachot%202a

• https://www.sefaria.org.il/api/links/berachos%202a

• https://www.sefaria.org.il/api/links/Berachos%202a

• https://www.sefaria.org.il/api/links/Berakhot%202a

• https://www.sefaria.org.il/api/links/berakhot%202a

• Example 3: Moed Katan 2b

• https://www.sefaria.org.il/api/links/moed%20katan%202b (no results)

• https://www.sefaria.org.il/api/links/Moed%20katan%202b (no results)

• https://www.sefaria.org.il/api/links/Moed%20Katan%202b (Results)

• Other: Yoma, Sukka, Sanhedrin, etc all work even if first letter is lowercase.

I was looking for where this is, but it seems it's about populating the search index.
