neighborsPerNode property
Aka "M": the max number of connections per node (default: 30). Higher numbers increase the graph connectivity, which can lead to more accurate search results. However, higher numbers also increase the indexing time and resource usage. Try e.g. 16 for faster but less accurate results, or 64 for more accurate results. Changing this value causes re-indexing.
