我在这里看到了一些关于为相应的 MySQL 列数据类型选择正确的字段类型的问题,但我的问题有点奇怪。我在 MySQL 类型的帖子中有一个专栏text
,我已经尝试field-type
在 Solr 中对应它,schema.xml
例如string, text, text-ws
。但每当我使用 DIH 导入它时,它都会作为 BLOB 对象导入。我检查了一下,这件事只发生在类型列text
而不是varchar
(它们被索引为字符串)。因此,posts 字段无法搜索。
在反复搜索失败后,我*:*
在 Solr 上进行查询搜索时发现了这个问题。示例响应:
<result name="response" numFound="223" start="0" maxScore="1.0">
<doc>
<float name="score">1.0</float>
<str name="solr_post_bio">[B@10a33ce2</str>
<date name="solr_post_created_at">2011-02-21T07:02:55Z</date>
<str name="solr_post_email">test.account@gmail.com</str>
<str name="solr_post_first_name">Test</str>
<str name="solr_post_last_name">Account</str>
<str name="solr_post_message">[B@2c93c4f1</str>
<str name="solr_post_status_message_id">1</str>
</doc>
