 * A lightweight search service that provides basic string-based matching for MCP tools.
 *
 * This service is designed for small to medium-scale deployments (50-200 tools) where
 * performance requirements are modest (<100ms response time) and full-text search
 * capabilities are not required. It implements a simple scoring algorithm based on
 * exact matches, prefix matches, substring matches, and description matches.
 *
 * The search is case-insensitive and returns results sorted by relevance score in
 * descending order. Tools with higher scores appear first in the results.
 *
 * Use cases:
 * - Quick tool discovery in development environments
 * - Basic search functionality for independent developers
 * - Lightweight alternative when advanced search features are not needed
 *
 * For larger scale deployments or when fuzzy search is required, consider using
 * the SearchCoreService instead.

    /**
     * Performs a case-insensitive search across all available MCP tools and returns
     * ranked results based on relevance scoring.
     *
     * The scoring algorithm works as follows:
     * - Exact name match: +10 points
     * - Name starts with query: +5 points
     * - Name contains query: +3 points
     * - Description contains query: +1 point
     *
     * Results are filtered to only include tools with a score greater than 0,
     * and are sorted by score in descending order (highest relevance first).
     *
     * @param query - The search query string. If empty or whitespace only,
     *                returns all tools with a score of 1.
     * @returns An array of SearchResult objects containing the matching tools
     *          and their relevance scores, sorted by score in descending order.
     *
     * @example
     * // Search for tools containing "find"
     * const results = simpleSearchService.search("find");
     * console.log(results[0].tool.name); // Highest scoring tool name
     * console.log(results[0].score);     // Relevance score (e.g., 10 for exact match)
     *
     * @example
     * // Get all tools (empty query)
     * const allTools = simpleSearchService.search("");
     * console.log(`Total tools: ${allTools.length}`);
     *
     * @example
     * // Case-insensitive search
     * const results1 = simpleSearchService.search("FIND");
     * const results2 = simpleSearchService.search("find");
     * // results1 and results2 will be identical
