Mongodb problem - Index key contains an illegal field name: field name starts with '$' AND text index required for $text query

[olegs18]

Reason for this issue

1. At startup, it is observed:
   MongoError: Index key contains an illegal field name: field name starts with '$'
   Like this #227 .
2. Also the search does not work in the forum and blog. The following is displayed: text index required for $text query
   LOG (console.log(conditions, options);):
   ↑ Request /api/posts → postIndex(forumTopic) 0.014s Size: 0kb POST:200
   conditions: {
   source: 'factor',
   status: 'published',
   '$text': { '$search': 'find text' }
   }
   options: {
   sort: {
   pinned: 'descending',
   contributedAt: 'descending',
   updatedAt: 'descending'
   },
   limit: 29,
   skip: 0,
   page: 1,
   order: 'latest',
   time: 'all-time',
   search: 'find text'
   }
   Steps to Reproduce
3. Run command: npx factor dev
4. Find text: http://localhost:3000/forum?search=find text

Thanks

Partially fixed in commit, MongoDB has changed something in regard to text indexes apparently.
