Subject Solr Import
Date Mon, 24 Sep 2018 06:43:26 GMT
Hi Experts,
Good Day!

We are having Solr 7.4 installed in our premise and we are planning to do
indexing of xml file. I am using data import handler to do the indexing,
but I had few queries on the indexing.
1.  Within a doc tag, there are multiple store, but the Solr response
contains only one *store value.*  With the below structure, Solr is not
accepting the xml, so when I changed the xml structure, I was able to
import the xml file to the Solr using the post tool and got *all *the value
of store which was comma separated.

*Snippet of the xml import file. *


*Snippet of the data-config.xml *

  <entity name="f" processor="FileListEntityProcessor"
fileName="ProductFeed20180924-001434-719.xml$" recursive="true"
rootEntity="false" dataSource="null" transformer="DateFormatTransformer"

      <!-- this processor extracts content using Xpath from each file found
      <entity name="nested" processor="XPathEntityProcessor"
forEach="/ProductFeedRetailToSOLR   |  ProductFeedRetailToSOLR/doc |
/metadata" url="${f.fileAbsolutePath}" >
              <field column="sku" xpath="/ProductFeedRetailToSOLR/doc/sku"/>
              <field column="store_s" xpath="/MT_ProductFeed/doc/store"/>

          What changes needs to be done to the data-config.xml so that we
have the response similar to the output that we get while using the post
script, that is to get *all the values of the store* that is comma
separated in the Solr response for each document.

2. Delta indexing of xml file.
We would be provided with an xml file and that would be imported to Solr
using full-import during the first import. Subsequently we would be
provided with changes made to the xml file (will be provided as an delta
file) and I would need to import just the changes to the Solr using
delta-import. When I click on delta-import, I do not see any update to the
Solr response.
Please guide us how we can achieve delta-import for *xml *file.

Thanks for the time and advice in advance.
