I'm new at solr and trying to index database with solr 6.5.1 + postgresql.
Finally it looks successful to index the database.
DataImport screen shows
Indexing completed. Added/Updated: 0 documents. Deleted 0 documents. (Duration: 21m 13s) Requests: 1 , Fetched: 19,736,915 15,504/s, Skipped: 0 , Processed: 0 Started: about an hour ago
However nothing is showing on Query screen when I pressed "Execute Query" button.
{
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"*:*",
"indent":"on",
"wt":"json",
"_":"1497333923963"}},
"response":{"numFound":0,"start":0,"docs":[]
}}
my database configuration (db-data-config.xml) is like as below.
<dataConfig>
<dataSource driver="org.postgresql.Driver" url="jdbc:postgresql://xxx.xx.xxx.xx:5432/xxxxx" user="xxxxx" password="xxx" />
<document>
<entity name="pubmed" query="select pmid, article_title, abstract from pubmed_xml">
<field column="pmid" name="pmid" />
<field column="article_title" name="article_title" />
<field column="abstract" name="abstract" />
</entity>
</document>
</dataConfig>
Could you guys give me some tips for fixing this issue ?
Thank you in advance.
If you check your schema.xml file, you'll see an entry as follows: <uniqueKey>id</uniqueKey>. This defines the solr field id to be the unique field which is mandatory for all documents in the index. In case you want to use a different field, change the uniqueKey entry and ensure that that particular field (pmid in your case) is defined in the schema.
