mergeFilters

  • mergeFilters(defaultFilter, generatedFilter, mergeType?, forceDefaultFilter?): undefined | {}

  • Merges two filters into one. If both filters are empty, returns undefined. If one filter is empty or the merge type is 'replace', returns the other filter. If the merge type is 'and' or 'or', returns a new filter with the merged results. Throws an error for unknown merge types.

    Parameters

    • defaultFilter: undefined | {}

      The default filter to merge.

    • generatedFilter: undefined | {}

      The generated filter to merge.

    • mergeType: string = "and"

      The type of merge to perform. Can be 'and', 'or', or 'replace'. Defaults to 'and'.

    • forceDefaultFilter: boolean = false

      If true, the default filter is always returned if the generated filter is empty. Defaults to false.

    Returns undefined | {}

    A merged QdrantFilter, or undefined if both filters are empty.

visitComparison

  • visitComparison(comparison): {}

  • Visits a comparison and returns a QdrantCondition. The value is casted to the correct type. The attribute is prefixed with "metadata.", since metadata is nested in the Qdrant payload.

    Parameters

    • comparison: Comparison

      The comparison to visit.

    Returns {}

    A QdrantCondition.

    visitOperation

    visitStructuredQuery

    • visitStructuredQuery(query): unknown

    • Visits a structured query and returns a VisitStructuredQueryOutput. If the query has a filter, it is visited.

      Parameters

      • query: StructuredQuery

        The structured query to visit.

      Returns unknown

      An instance of VisitStructuredQueryOutput.
