Creating a vector index using the example in the documentation fails

[odysseaspenta]

I am using v25.7.1 and when trying to create a vector index using the example from the documentation, I get an error.

import database cc.en.300.vec.gz with distanceFunction = 'cosine', m = 16, ef = 128, efConstruction = 128;

The error message is about a missing parameter that is required. Here is the relevant part of the stack trace.

Caused by: com.arcadedb.integration.importer.ImportException: Error on importing Word2Vec datasource at com.arcadedb.integration.importer.format.Word2VecImporterFormat.load(Word2VecImporterFormat.java:55) at com.arcadedb.integration.importer.Importer.loadFromSource(Importer.java:107) at com.arcadedb.integration.importer.Importer.load(Importer.java:53) ... 14 more Caused by: com.arcadedb.index.IndexException: Vertex vector property name is missing from vector index declaration at com.arcadedb.schema.VectorIndexBuilder.create(VectorIndexBuilder.java:95) at com.arcadedb.schema.VectorIndexBuilder.create(VectorIndexBuilder.java:42) at com.arcadedb.integration.importer.vector.TextEmbeddingsImporter.run(TextEmbeddingsImporter.java:150) at com.arcadedb.integration.importer.format.Word2VecImporterFormat.load(Word2VecImporterFormat.java:52)

Changing the command to the following, successfully creates an index.

import database cc.en.300.small.vec.gz with distanceFunction = 'cosine', m = 16, ef = 128, efConstruction = 128, vertexType = Word, edgeType = Proximity, vectorProperty = vector, idProperty = name;

This should either be fixed in the documentation or the importer should have default values for some of these parameters. I could help with fixing this.

This issue is not relevant anymore because of the new LSM Vector implementation: #2529
