SOLR - Define fields in DIH configuration file dynamically

["kobe.free.world@gmail.com" <ko...@gmail.com>]

Hello All,

Is there a way to manage (add/ remove) fields in the data import handler
configuration file dynamically through any API/ Library like SolrNet?

Thanks

You can use dynamic fields as described here:
http://wiki.apache.org/solr/SchemaXml#Dynamic_fields
Many examples are available by searching Google for
"solr schema dynamic fields".

Thanks for your reply.

Please let me know, if it is also possible to define the complete set/list
of the fields dynamically in the DIH config file. In our scenario, we will
be required to change the set/list of the fields based on business needs
regularly.

There are 3 approaches I can think of:

1. You can generate a new data-config.xml for each import.  With Solr 4.0 and later, DIH re-parses your data-config.xml and picks up any changes automatically.

2. You can parameterize nearly anything in data-config.xml, add the parameters to your request URL like:
/solr/dataimport?command=full-import&key=value
...then use ${dataimporter.request.key} in your data-config.xml

3. You can put optional sections into sql queries, then use parameters to insert comment strings:
/solr/dataimport?command=full-import&openComment=/*&closeComment=*/
<entity query="
 select id, something${dataimporter.request.openComment},optionalStuff${dataimporter.request.closeComment} from foo
"/>

Not sure if this is the answer to your question.  If not, give more details.
