 Prisma Client supports full-text search for **PostgreSQL** databases in versions 2.30.0 and later, and **MySQL** databases in versions 3.8.0 and later. With full-text search enabled, you can add search functionality to your application by searching for text within a database column.

+## Full-text search with raw SQL
+
+Full-text search is currently in Preview and due to a [known issue](https://github.com/prisma/prisma/issues/8950), you may be seeing slow search queries. If that's the case, you can optimize your query using [raw SQL](/orm/prisma-client/queries/raw-database-access).

+### PostgreSQL
+
+In PostgreSQL, you can use `to_tsvector` and `to_tsquery` to express your search query:
+
+```ts
+const term = `cat`
+const result =
+  await prisma.$queryRaw`SELECT * FROM "Blog" WHERE to_tsvector('english', "Blog"."content") @@ to_tsquery('english', ${term});`
+```
+
+> **Note**: Depending on your language preferences, you may exchange `english` against another language in the SQL statement.
+
+If you want to include a wildcard in your search term, you can do this as follows:
+
+```ts
+const term = `cat:*`
+const result =
+  await prisma.$queryRaw`SELECT * FROM "Blog" WHERE to_tsvector('english', "Blog"."content") @@ to_tsquery('english', ${term});`
+```
+
+### MySQL
+
+In MySQL, you can express your search query as follows:
+
+```ts
+const term = `cat`
+const result =
+  await prisma.$queryRaw`SELECT * FROM Blog WHERE MATCH(content) AGAINST(${term} IN NATURAL LANGUAGE MODE);`
+```
