In lesson 11, Jeremy uses the **angulardist** space for similarity measure using nmslib.

Is there a list of spaces which nmslib supports somewhere?

In lesson 11, Jeremy uses the **angulardist** space for similarity measure using nmslib.

Is there a list of spaces which nmslib supports somewhere?

There is no much documentation in nmslib itself on it, but I guess this is ultimate list: https://github.com/nmslib/nmslib/blob/d3cc0899604698f1e78867cf5396031268db55f1/similarity_search/include/space/space_scalar.h#L31

Yeah I found this. But that doesnâ€™t seem to be all the spaces

It lists:

```
#define SPACE_COSINE_SIMILARITY "cosinesimil"
#define SPACE_ANGULAR_DISTANCE "angulardist"
#define SPACE_NEGATIVE_SCALAR "negdotprod"
```

But https://github.com/nmslib/nmslib/tree/master/python_bindings/notebooks has at least the following:

```
space='jaccard_sparse'
space='l2sqr_sift'
space='cosinesimil_sparse'
space='kldivgenfast'
space='l2'
```

Here on page 31: https://github.com/nmslib/nmslib/blob/master/manual/manual.pdf

However, jaccard seems to be missingâ€¦
