Re: Blank/Null value search in term filter
If you only have 3 values, can you do negative queries on the ones you want to skip?

Thanks Ahmet for your response and nice suggestion. But, I was looking if there any way out without making any configuration change. Please suggest.

Re: Blank/Null value search in term filter
Hi Kishore, You can employ an impossible token value (say XX) for null values. This can be done via default value update processor factory. You index some placeholder token for null values. fq={!terms f='queryField' separator='|'}A|XX would fetche docs with A or null values.

Example: fq={!terms f='queryField' separator='|'}A|B A, B, C are the possible field values for solr field "queryField". There can docs with null values for the same field. Now, how can I create a term filter in above fashion that fetches docs with A or null values. Please suggest. Regards Kamal
Blank/Null value search in term filter
Hi, We are using solr 5.4.1. We are using term filter for multiple value matching purpose. Example: fq={!terms f='queryField' separator='|'}A|B A, B, C are the possible field values for solr field "queryField". There can docs with null values for the same field. Now, how can I create a term filter in above fashion that fetches docs with A or null values. Please suggest. Regards Kamal
