If any part of a dimension value contains the value specified in this search query spec, regardless of case, a “match” occurs. The grammar is:
{ "type" : "insensitive_contains", "value" : "some_value" }
If any part of a dimension value contains any of the values specified in this search query spec, regardless of case, a “match” occurs. The grammar is:
{ "type" : "fragment", "values" : ["fragment1", "fragment2"] }
