Hi,
I am new to solr, lucene. In my project I want to copy index
directory based on some query (copy may not copy the whole index
directory). I came across a backup script in solr/bin folder but it
seems to be copying the whole index directory.
My query is, what is the procedure for copying a part of the index.
Is it like - do a query, get all the fields, make a new index with
those queried results? Or is there any other way ?
You can't easily copy parts of the physical file. I suggest
performing the query, fetching some unique key (application-specific),
and re-indexing those documents from your original source. It can be
done through Solr too, but you have to be careful to store all the
relevant fields to being with.
Thanks for the reply. I have one more query. My doubt is where to
re-index (location of the index directory) ? For this should I run
another instance of solr? Is this the preferred approach ?
