Pinecone 数据库全文搜索正式可用
精选理由
Pinecone 把 BM25 关键词搜索塞进了同一个向量索引里，查零件号这种精确字符串终于不用再翻语义搜索的乱序结果了。
Pinecone Database 的全文搜索功能已正式发布（GA）。该功能使用 BM25 关键词排名，与向量运行在同一个索引中。语义搜索难以精确匹配零件编号等字面字符串，而全文搜索能把完全匹配的结果排在列表顶部。开发者在同一索引里即可同时获得语义检索和精确关键词匹配能力。

ICYMI: Full-text search is generally available in Pinecone Database.
Semantic search doesn't find literal strings well. Query a literal string like part number and all the similar part numbers score about as high as the one you actually wanted, and nothing in the results tells them apart.
Full-text search solves this. BM25 keyword ranking runs in the same index as your vectors. So, exact matches are returned and ranked at the top of the list.
