-- ============================================================
|
||
-- EKB Schema MVP 索引创建脚本
|
||
-- 执行时机：prisma db push 之后手动执行
|
||
-- 说明：MVP 阶段只创建 HNSW 向量索引，pg_bigm 索引在 Phase 2 创建
|
||
-- ============================================================
|
||
|
||
-- 1. 确保 pgvector 扩展已启用
|
||
CREATE EXTENSION IF NOT EXISTS vector;
|
||
|
||
-- 2. HNSW 向量索引（语义检索核心）
|
||
-- 参数说明：m=16 每层最大连接数，ef_construction=64 构建时搜索范围
|
||
CREATE INDEX IF NOT EXISTS idx_ekb_chunk_embedding
|
||
ON "ekb_schema"."ekb_chunk"
|
||
USING hnsw (embedding vector_cosine_ops)
|
||
WITH (m = 16, ef_construction = 64);
|
||
|
||
-- 3. JSONB GIN 索引（可选，提升查询性能）
|
||
CREATE INDEX IF NOT EXISTS idx_ekb_doc_metadata_gin
|
||
ON "ekb_schema"."ekb_document"
|
||
USING gin (metadata jsonb_path_ops);
|
||
|
||
CREATE INDEX IF NOT EXISTS idx_ekb_doc_structured_gin
|
||
ON "ekb_schema"."ekb_document"
|
||
USING gin (structured_data jsonb_path_ops);
|
||
|
||
-- 4. 标签数组索引
|
||
CREATE INDEX IF NOT EXISTS idx_ekb_doc_tags_gin
|
||
ON "ekb_schema"."ekb_document"
|
||
USING gin (tags);
