Methods and systems are provided to identify PCR duplicates of genetic sequence reads using inexact matching. More specifically, clustering of sequence reads based on inexact matching of both positional alignment coordinates and / or molecular barcodes are described. Samples are sequenced to generate unclustered sequence reads associated with a set of sorting features.

In an example embodiment, embeddings are used to securely search sensitive encrypted data stored in a database without the need to retrieve and decrypt all data in a volume. Specifically, a piece of text is embedded into an embedding, which is then stored in a vector database. Then the piece of text can be encrypted and stored in another database. A linkage between the embedding and the ciphertext can also be stored. When a search is performed, one or more keywords from the search can be embedded and the keyword embedding can be compared to the embeddings in the vector database to locate similar embeddings. The ciphertexts corresponding to those similar embeddings can then be retrieved from the other database and decrypted. The decrypted ciphertexts can then be searched based on the keywords to find exact matches.
