Erik Hatcher commented on SOLR-6937:
------------------------------------
[[email protected]], I tried this:
{code}
public class NormalizeFieldNameUpdateProcessorFactory extends
FieldMutatingUpdateProcessorFactory {
@Override
public UpdateRequestProcessor getInstance(SolrQueryRequest req,
SolrQueryResponse rsp, UpdateRequestProcessor next) {
return new FieldMutatingUpdateProcessor(getSelector(), next) {
@Override
protected SolrInputField mutate(SolrInputField src) {
src.setName(src.getName().replace(' ', '_'));
return src;
}
};
}
}
{code}
And got this error:
{code}
<lst name="error"><str name="msg">mutate returned field with different name:
field with spaces => field_with_spaces</str><str
name="trace">org.apache.solr.common.SolrException: mutate returned field with
different name: field with spaces => field_with_spaces...
{code}
Are there problems that would result when changing the name of a field in
FieldMutatingUpdateProcessor?
> In schemaless mode, field names with spaces should be converted

>
> Assuming spaces in field names are still bad, we should automatically convert
> them to not have spaces. For instance, I indexed Citibike public data set
> which has:
> {quote}
> "tripduration","starttime","stoptime","start station id","start station
> name","start station latitude","start station longitude","end station
> id","end station name","end station latitude","end station
> longitude","bikeid","usertype","birth year","gender"{quote}
> My vote would be to replace spaces w/ underscores.
