Periods in a node's name cause search results to be truncated

[ericlingit]

When a node's name contains a period (.), only the strings on the right-side of the period show up in the search result.

How to reproduce

1. Create an index

   HNSW.NEW test DIM 3
   

2. Add nodes

   HNSW.NODE.ADD test aaa.txt DATA 3 1.0 1.0 1.0
   HNSW.NODE.ADD test bbb.txt DATA 3 1.0 1.0 1.0
   HNSW.NODE.ADD test ccc.txt DATA 3 1.0 1.0 1.0
   

3. Search

   HNSW.SEARCH test K 3 QUERY 3 1.0 1.0 1.0
   

Expected output

[
    3,
    ['similarity', '-0', 'name', 'aaa.txt'],
    ['similarity', '-0', 'name', 'bbb.txt'],
    ['similarity', '-0', 'name', 'ccc.txt']
]

Actual output

[
    3,
    ['similarity', '-0', 'name', 'txt'],
    ['similarity', '-0', 'name', 'txt'],
    ['similarity', '-0', 'name', 'txt']
]
