The method to use to combine similar results. You can use this option when your index contains document sections or duplicate documents, to ensure that each document returns only a single result.
By default, when HPE Content Component combines multiple results, it returns the result with the highest relevance. You can use the Sort action parameter to use an alternative sorting method, in which case it returns the result that scores highest for your Sort method.
Combine to one of the following values:
Combine sections of the same document. HPE recommends this
When you index very long texts, HPE Content Component splits them up into sections and indexes each section as an individual document. Each section has its own document ID, but all sections of the document have the same document reference. This process improves the stability of the indexing process, and ensures that HPE Content Component returns only the most relevant sections of a text.
However, when multiple sections match a query, HPE Content Component might return multiple results that have the same document reference (for example, different pages of the same book), and if you set Print to
Combine results that have the same value in the specified ReferenceType field.
Avoid using the
Combine results that have the same hash value of their FieldCheckType field.
The FieldCheckType field holds a value that you use frequently to restrict results (for example, a field that stores category names). When HPE Content Component indexes a FieldCheckType field, it stores it in a fast-look-up table in memory, so that it can return it quickly.
Combine results that have the same value in a metadata field. You can use the following metadata fields:

By default, HPE Content Component combines any result documents that do not have a FieldCheckType field or the specified ReferenceType field into a single result. To return these results separately, set the CombineIgnoreMissingValue configuration parameter to

In this example, if several results derive from the same source text, HPE Content Component displays only the document section that has the highest relevance to the query text.
