Hi Hoss,
Thanks for your quick reply.
Below is my solr.xml configuration, and already set persistent to true.
<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true">
<cores adminPath="/admin/cores"
zkClientTimeout="${zkClientTimeout:15000}" hostPort="18000">
<core schema="schema.xml" shard="shard1" instanceDir="test1-ondeck/"
name="test1" config="solrconfig.xml" collection="test1-ondeck"/>
<core schema="schema.xml" shard="shard1" instanceDir="test1/"
name="test1-ondeck" config="solrconfig.xml" collection="test1"/>
</cores>
</solr>
For test1 and tets1-ondeck content, just copied from
example/solr/collection1
Then publish 1 record to test1, and query. it's ok now.
INFO: [test1] webapp=/solr path=/select
params={distrib=false&wt=javabin&rows=10&version=2&fl=id,score&df=text&NOW=1348195088691&shard.url=host1:18000/solr/test1/&start=0&q=*:*&isShard=true&fsv=true}
hits=1 status=0 QTime=1

Then use core admin console page to swap, and click reload for test1 and
test1-ondeck. if keep refresh query page, sometimes give 1 record,
sometime give 0 records.
And found the shardurl is different with the log which search before swap.
It’s shard.url=host1:18000/solr/test1-ondeck/| host1:18000/solr/test1/.
Below return 0
