OSS docs now own the full usage content for features that only run against an Enterprise deployment, since the client interface itself lives here; Enterprise docs keep only the parts specific to its own behavior. Sophon's overlay for these five pages is dropped since the OSS versions are now the complete reference. SQL Reference is restructured to match an object-type SQL manual (DDL by object, then DML, then DQL, then Expressions) instead of the old flat, loosely-ordered page list, absorbing the SQL client-connection guide and FTS-via-SQL examples into it.

## CREATE INDEX {#create}
|
|
|
|
```sql
|
|
CREATE INDEX ON documents (title)
|
|
```
|
|
|
|
<Note>
|
|
SQL `CREATE INDEX` covers **one column** and takes **no user-chosen name** --
|
|
the server names it. For a multi-column or explicitly-named index, or to
|
|
choose the algorithm, use the SDK's
|
|
[`create_index`](/indexing#choosing-an-index).
|
|
</Note>
|
|
|
|
<Note>
|
|
**Enterprise job type:** `create_ivf_pq`, `create_btree`, `create_fts`, and one
|
|
more per algorithm -- the type names which algorithm is building, not a
|
|
different feature. See [Build & Repair](/indexing/reindexing).
|
|
</Note>
|
|
|
|
## DROP INDEX {#drop}
|
|
|
|
```sql
|
|
DROP INDEX documents.title_idx
|
|
```
|
|
|
|
Takes the qualified `table.index` name. Find it with the SDK's
|
|
[`list_indices`](/indexing#choosing-an-index) if you created the index without
|
|
naming it yourself.
