Consider adding clear="field1,field2" feature for formatting results?

LDAP search offers a handy clear="field1,field2,..." feature whereby if the field does not exist in the LDAP record you won't get $field1 or $field2 etc. in your output - you'll get a blank instead. Would you consider adding this feature to SOLRSEARCH and SOLRFORMAT too? It would help in cases where - for example, the search is displaying form fields but some of the topics were created before one of the displayed fields existed in the form - so for those topics that form field is not defined and not indexed.

The basic functionality can also be achieved using an IF but clear= is a lot easier to write and read.

It is there. Just define the fields you need in the fields parameter. This does two things:

1. just request those fields specified in the response json
2. clear the listed $fields from the format string

Thanks Michael. I thought the fields parameter was only for efficiency in the json response. I didn't realize it would also help by clearing the fields.

My only other comment would be that since I'm using and displaying about 10 fields but only one of them is likely to be missing from some of the documents, I have a lot more typing to do than if I could just list the one field in a clear parameter. So a clear parameter might be a nice feature to add even if it can be accomplished another way.
