Hi All,

I am trying to write a search for extracting fields which are not matching with the lookup file or table. For example, I have the field named category and a lookup table with values similar to category in the index. Now I want to extract fields from the index which are not matching with values in the lookup table. Please help me in writing the search.

Thank you in advance

Generally, like this:

... NOT [|inputlookup MyLookup | fields MyFieldToNotMatch]

Just put your base search in place of the ellipsis ( ... ).

Can you provide name of fields in the index and all fields available in lookup?
