Steps

• Call SearchIndex.search("(")

Expected

• Blood type emojis 🅾️ 🅰️ 🅱️ should not match
• Flags 🇨🇨 🇲🇲 should not match

Actual

• Those 3 blood type and 2 flag emojis match

Notes

• Appears the problem is their names include parens
• e.g. A Button (blood Type) gets converted into ,a,button,(blood,type) for searching

Related problems

• Searching for burma should match 🇲🇲, and keeling should match 🇨🇨 , but that is not working right now either for the same reason

Proposal

• splitting name into searchable parts should also split by ( and )
