// RegisterPercolate allows the caller to register queries against an index, and then send percolate requests which include a doc, and
// getting back the queries that match on that doc out of the set of registered queries.
// Think of it as the reverse operation of indexing and then searching. Instead of sending docs, indexing them,
// and then running queries. One sends queries, registers them, and then sends docs and finds out which queries
// match that doc.
