<!-- Answer --> K-neighbor API（包括 AVA 客户端和服务端）目前不支持对顶点属性进行“谓词模糊匹配”（如模糊、正则、LIKE、contains、TEXT_CONTAINS 等）。K-neighbor API 的属性过滤仅支持精确值或标准 Gremlin 谓词（如 P.eq、P.gt、P.lte），不支持模糊、正则或 contains 风格的匹配，也没有相关配置或插件方式可以实现这一点。相关源码和接口文档均未发现支持模糊谓词的实现或扩展方式[[源码参考](https://github.com/apache/incubator-hugegraph-toolchain/blob/50a839469b1ad779115e371d0df378116638e9e1/hugegraph-client/src/main/java/org/apache/hugegraph/structure/traverser/KneighborRequest.java)][[API参考](https://github.com/apache/incubator-hugegraph-toolchain/blob/50a839469b1ad779115e371d0df378116638e9e1/hugegraph-client/src/main/java/org/apache/hugegraph/api/traverser/KneighborAPI.java)]。 如果需要模糊匹配（如属性包含某关键词、分词、逗号分割项等），推荐用 Gremlin 查询配合 Search 索引（如 CONTAINS、TEXT_CONTAINS）先筛选出目标顶点，再用这些顶点作为 source 执行 K-neighbor 遍历。例如： ```java // 先用 Gremlin 查询模糊匹配 g.V().hasLabel("org").has("alias", CONTAINS, "广州软件").limit(10) // 或 g.V().hasLabel("org").has("alias", TEXT_CONTAINS, "广州软件").limit(10) ``` 需要为该属性建立 Search 索引，且属性类型为 SET/LIST 时效果最佳[[用法说明](https://github.com/apache/incubator-hugegraph/issues/2753)]。 总结：K-neighbor API 只支持精确或范围谓词过滤，不支持模糊谓词。模糊需求建议用 Gremlin + Search 索引先查出顶点，再用 K-neighbor API 做遍历。 <!-- Dosu Comment Footer --> *To reply, just mention my name [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
