How do I get empty fields in SOLR indexed for a schemaless collection?

How do I get empty fields in SOLR indexed? I am using solr 7.2.0

I am using schemaless SOLR to try to index everything as string, but for files with empty fields, those fields do not get indexed. Is there a way to get them to show up?

col1,col2,col3
a,,1
d,e,
g,h,3

for example column 1 shows up as 

{
"col1":"a",
"col3":"1",
}

I'm trying to also get col2 to show up. in my solrconfig.xml i have this 

  <dynamicField name="*" type="text_general" indexed="true" stored="true" required="true" default="" />

and I have any traces of the remove-blank processor removed from my config. I've reloaded and deleted/recreated by collection multiple times. Is there a solution for this?

Solution

  • The CSV import module has its own option to keep empty fields - f.<field name>.keepEmpty=true.

    If you don't give that option, the CSV handler will never give the empty field value to the next step in your indexing process.

    Giving f.col2.keepEmpty=True as an URL argument should at least give you a better starting point.
