requiresPositiveClause(groupLevelOperatoropt) → {boolean}

For "negative" Filters (filter models where exclude is set to true), detects whether the query requires an additional "positive" query phrase in order to avoid the problem of pure negative queries returning zero results. If this Filter is not part of a collection of Filters, assume it needs the positive clause. If this Filter is part of a collection of Filters, detect whether there are other, "positive" filters in the same query (i.e. filter models where exclude is set to false). If there are other positive queries, then an additional clause is not required. If the Filter is part of a pure negative query, but it is not the last filter, then don't add a clause since it will be added to the last, and only one is required. When looking for other positive and negative filters, exclude empty filters and filters that use any of the identifier fields, as these are appended to the end of the query.
Parameters:
Name Type Attributes Description
groupLevelOperator string <optional>
 "AND" or "OR". The operator used in the parent Filters collection to combine the filter query fragments together. If the group level operator is "OR" and this filter has exclude set to TRUE, then a positive clause is required.
Inherited From:
Source:
See:
Returns:
returns true of this Filter needs a positive clause, false otherwise
Type
boolean
