[DOC]: vector search tutorial issues

[wuhu]

What's wrong?

(version: 0.5.1)

Here are some things I noticed reading https://docs.superduper.io/docs/tutorials/vector_search

• Some of the links are broken.

  • https://docs.superduper.io/docs/ai_integrations/sentence_transformers
  • https://docs.superduper.io/api/ext/sentence_transformers/
    are dead (possibly more, I didn't check all).

• It would be useful to mention that vector search requires an extra package (I got a ModuleNotFoundError and had to figure out what was going on)

• db.apply(...) fails with

         137     def _pre_create(self, db: Datalayer, startup_cache: t.Dict = {}):
         138         assert isinstance(self.indexing_listener, Listener)
         139         assert hasattr(self.indexing_listener, 'output_table')
         140         assert hasattr(self.indexing_listener.output_table, 'schema')
         141         assert isinstance(self.indexing_listener, Listener)
         142         assert isinstance(self.indexing_listener.output_table, Table)
         143         try:
         144             assert isinstance(
         145                 self.indexing_listener.output_table.schema,
         146                 Schema,
         147             )
         148             next(
         149                 v
         150                 for v in self.indexing_listener.output_table.schema.fields.values()
         151                 if hasattr(v, 'shape') and v.shape is not None
         152             )
         153         except StopIteration:
    --> 154             raise Exception(
         155                 f'Couldn\'t get a vector shape for '
         156                 f'{self.indexing_listener.output_table.schema.huuid}'
         157             )
         158```
  
  
  

How could it be better?
