MongoDB Search Strategy

Is your feature request related to a problem? Please describe.

Due to the DefaultSeachPlugin within @vendure/core not having an implemented MongoDB Search Strategy, even if I configure VendureConfig correctly using the TypeORM MongoDB Connection settings (as mentioned in https://github.com/vendure-ecommerce/vendure/issues/132#issuecomment-517197724 from 2019), I still receive the following error.

Looking at #505 I could modify the following line so I no longer get the error.database-not-supported-by-default-search-plugin error, although that doesn’t add the functionality magically.

https://github.com/vendure-ecommerce/vendure/blob/3460536121b43e188824d38321dfe7f59795e740/packages/core/src/plugin/default-search-plugin/fulltext-search.service.ts#L110-L128

Describe the solution you’d like A MongoDB Search Strategy be implemented within @vendure/core’s DefaultSeachPlugin.

Describe alternatives you’ve considered Being pointed to an already existing implementation of this, or a neat work around. Failing all of the above, I can just hackily change the switch case.

Additional context N/A

If you know what either TypeORM doesn’t cover, or what you’ve had to write on top of / extend TypeORM for custom functions (like the Search Strategies, where you’ve written implementations for mariadb, better-sqlite3 and postgres), I would be interested in looking into what it would take to make MongoDB reach the minimum compatibility level to function.

Just had a look through the TypeORM issues and it seems like the MongoDB driver does not support:

• Relations: https://github.com/typeorm/typeorm/issues/655
• Transactions: https://github.com/typeorm/typeorm/issues/3051

which are absolute show-stoppers right there. Unless those features get proper support, there’s basically no possibility that Vendure will work with Mongo.
