search_nodes

Query entities in the MCP knowledge graph using Elasticsearch syntax. Filter by types, include observations, and sort results to find relevant information for specific questions, respecting zone isolation.

Instructions

Search entities using ElasticSearch query syntax. Supports boolean operators (AND, OR, NOT), fuzzy matching (~~), phrases ("term"), proximity ("terms"~~N), wildcards (*, ?), and boosting (^N). Examples: 'meeting AND notes', 'Jon~~', '"project plan"~~2'. All searches respect zone isolation.
