Searches the official Parallax documentation (docs.parallaxprotocol.org: running a node, mining, wallets, JSON-RPC, the PVM, networking, Tor, protocol concepts) and the Parallax Improvement Proposals (PIP-0002 ASERT difficulty, PIP-0003 DNS discovery, PIP-0004 fee estimation, PIP-0005 UPnP, PIP-0006 TCP discovery). Use it whenever a question is about how Parallax works or how to do something with it: Parallax differs from Ethereum and Bitcoin in many details (no EIP-1559, Berlin EVM, XHash, ASERT, its own client flags), so look it up rather than answer from general knowledge. Returns the best matches, each with title, path, a summary and an excerpt around the matching text; read a page in full with read_doc and cite its url. "query" is keywords or a question, such as "mining pool setup" or "how does the fee estimator work"; "kind" limits results to "docs" or "pip".
