Summary:
Special characters in a search query on Minecraft.net cause the suggestions box to disappear and the system to yield invalid search results.

Affects currently Live Content:
Yes

Impact:

Makes it difficult to discover products with special characters in product names.

Repro Steps:

1. Open the Minecraft.net Marketplace page.
2. Search for something, let's search for "SECURITY++" (no quotes).
3. Observe that the list of suggestions disappears.
4. Click search or hit enter.
5. Observe that the results have nothing to do with the search terms entered.

Observed Results:

The search box disappears when "+" is in the search term. The search results are invalid.

Expected Results:
"+" is a common symbol used in Minecraft DLC names. It should work in search suggestions and should yield the correct search results.

Notes:

We recommend encoding "+" as %2B and adjusting the API to handle encoded characters (so it doesn't get treated as a space in a query string when the search is dispatched to the productmanagement API). Currently, any + character sent in the API will return an empty response: https://www.minecraft.net/bin/minecraft/productmanagement.productsbydescrpition.json?locale=en-us&term=SECURITY++ 

We also tried to search "Security Add-On" as a workaround, and "SECURITY++ Add-On" does not appear in the results. This makes it very difficult to find products that have "+" in the product name, because "SECURITY" doesn't yield either.
