The general process to build a search application using Vertex AI Vector Search involves the following steps:

1. Encode Data to Embeddings: The first step in building a search application is to encode your data into embeddings. This involves converting your raw data, which could be in various formats such as text, images, or audio, into a numerical representation that can be understood by machine learning models. This is typically done using techniques such as one-hot encoding or word embeddings for text data, or convolutional neural networks for image data.

2. Build an Index: Once your data is encoded into embeddings, the next step is to build an index. This involves organizing your embeddings in a way that allows for efficient search and retrieval. There are various indexing algorithms available, such as k-d trees or hashing, and the choice of algorithm will depend on the specific requirements of your application.

3. Search Results: The final step in building a search application is to implement a search function that can retrieve relevant results from your index based on a given query. This involves comparing the query to the embeddings in your index and returning the most similar results. This is typically done using a similarity measure such as cosine similarity or Euclidean distance.

So, the correct answer is "Encode data to embeddings, build an index, and search results."
