Hello Guys,
We had a requirement to search existing lucene indexes and configure to
indexing new data.
1. Installed apache-solr-3.6.1 and setup multicore for the existing indexes.
2. Solr is running on windows platform with tomcat 7 64 bit
3. Coll1 and Coll2 has old lucene index files and new indexing data will be
stored in coll3
<solr persistent="false">
<cores adminPath="/admin/cores" sharedLib="lib" defaultCoreName="coll3">
<core name="coll1" instanceDir="1" />
<core name="coll2" instanceDir="2" />
<core name="coll3" instanceDir="3" />
</cores>
</solr>
4.Now we are indexing data from CSV file thru curl
curl http://localhost:8080/solr/update/csv -F "stream.file=D:\eighth.csv" -F
"commit=true" -F "optimize=true" -F "encapsulate=""
While searching all the cores with shards, the new core is not considered.
- We have maintained same conf and schema across all cores
http://94.101.147.150:8080/solr/select/?q=*%3A*&version=2.2&start=0&rows=10&indent=on&shards=localhost:8080/solr/coll1,localhost:8080/solr/coll2,localhost:8080/solr/coll3
We observe that there is difference in index format, got to know thru luke
browser.
Old Lucene Indexes: Index format -9 (Lucene 2.9)
New Lucene Indexes: Index format -11(Lucene 3.1)
1. How can we make these 3 cores work together?
2. Is there any option to migrate the old Index format 2.9 to newer?
This has been a show stopper for us, any help would be really appreciated.
Regards,
Ravi
