Full-text-search not working when the query is multiple strings

Bug description

Full-text-search not working when the query is multiple words, works fine when it’s a single word being passed into my Prisma query:

const results = await prisma.post.findMany({
      where: {
        body: {
          search: `post`, // works
        },
      },
    });

const results = await prisma.post.findMany({
      where: {
        body: {
          search: `second post`, // throws an error
        },
      },
    });

I get the following error:

PrismaClientUnknownRequestError3 [PrismaClientUnknownRequestError]: 
Invalid `prisma.post.findMany()` invocation:


  Error occurred during query execution:

How to reproduce

Reproduction: https://github.com/m-abdelwahab/prisma-full-text-search

Clone repo, install dependencies, run seed script, go to http://localhost:3000 and try some queries

Maybe I’m doing something wrong that I’m not aware of

Expected behavior

Should work normally and return results that contain my query.

My workaround is to replace whitespace with underscore, it works for tabs, newline, and consecutive white spaces.

{
  search:query.replace(/[\s\n\t]/g, '_')
}

[matthewmueller]

The workaround today is to pre-process your queries, for example:

const results = await prisma.post.findMany({
  where: {
    body: {
      search: "second post".split(" ").join(" & "),
    },
  },
});
