HNSW cannot index more than one vector per relation

[chuanqisun]

Repro steps is based on v0.6 release note, with dimension reduced to 1 for demo purpose

:create product {
    id 
    => 
    name, 
    description, 
    price, 
    name_vec: <F32; 1>, 
    description_vec: <F32; 1>
}

::hnsw create product:semantic{
    fields: [name_vec, description_vec], 
    dim: 1, 
    ef: 16, 
    m: 32,
}

?[id, name, description, price, name_vec, description_vec] <- [[1, "name", "description", 100, [1], [1]]]

:put product {id => name, description, price, name_vec, description_vec}

Results

  × when executing against relation 'product'
  ╰─▶ Cannot find tuple [1]

I tried removing the description_vec and it works as expected.

:create product {
    id 
    => 
    name, 
    description, 
    price, 
    name_vec: <F32; 1>,
}

::hnsw create product:semantic{
    fields: [name_vec], 
    dim: 1, 
    ef: 16, 
    m: 32,
}

?[id, name, description, price, name_vec] <- [[1, "name", "description", 100, [1]]]

:put product {id => name, description, price, name_vec}

This is now fixed
