notePrefix does not search for full prefix

See original GitHub issue

Subject of the issue

searchForTransactions() with notePrefix() does not seem to perform a search of the full prefix provided in order to narrow down the number of results.

Steps to reproduce

I have made 3 transactions with 3 different prefixes:
1. MydApp:MD01:0.0.1:
2. MydApp:MD02:0.0.1:
3. MydApp:MD03:0.0.1:

Expected behaviour

The Indexer API should return only transactions whose prefix matches the search (in base64: TXlkQXBwOk1EMDM6MC4wLjE6), instead it returns all transactions for my address, including one with a completely different notes prefix.

const enc = new TextEncoder();
const prefix = enc.encode("MydApp:MD03:0.0.1:"); // TXlkQXBwOk1EMDM6MC4wLjE6
const s = Buffer.from(prefix).toString("base64");

const address = "NLOMMDJQCRKOBMFNWVCHDEFD3ZXKBI24MHXEBMEVALPMMZNMOHMTCOYNJA";
const response = await algoIndexer.searchForTransactions()
            .txType("pay").address(address).notePrefix(s).do();

Actual behaviour

Only txID I2TRV4AVORWXJ2ZU2N77F5VDV35YHTWHVOV3PJJCYTHY7NNGG2QA should be returned, instead I get:

According to this tutorial searchForTransactions() can combine multiple search parameters so, unless I misunderstood its usage, I should be using it correctly. Is this the intended behavior? Otherwise, what am I missing?
