      public List<String> collectionIds()
      Gets the collectionIds.

    • filter

      public String filter()
      Gets the filter.

      A cacheable query that excludes documents that don't mention the query content. Filter searches are better for metadata-type searches and for assessing the concepts in the data set.

    • query

      public String query()
      Gets the query.

      A query search returns all documents in your data set with full enrichments and full text, but with the most relevant documents listed first. Use a query search when you want to find the most relevant search results.

      Returns:
      the query

    • naturalLanguageQuery

      public String naturalLanguageQuery()
      Gets the naturalLanguageQuery.

      A natural language query that returns relevant documents by utilizing training data and natural language understanding.

      Returns:
      the naturalLanguageQuery

    • aggregation

      public String aggregation()
      Gets the aggregation.

      An aggregation search that returns an exact answer by combining query search with filters. Useful for applications to build lists, tables, and time series. For a full list of possible aggregations, see the Query reference.

      Returns:
      the aggregation

    • count

      public Long count()
      Gets the count.

      Number of results to return.

      the count

    • xReturn

      public List<String> xReturn()
      Gets the xReturn.

      A list of the fields in the document hierarchy to return. If this parameter not specified, then all top-level fields are returned.

      the xReturn

    • offset

      public Long offset()
      Gets the offset.

      The number of query results to skip at the beginning. For example, if the total number of results that are returned is 10 and the offset is 8, it returns the last two results.

      Returns:
      the offset

    • sort

      public String sort()
      Gets the sort.

      A comma-separated list of fields in the document to sort on. You can optionally specify a sort direction by prefixing the field with `-` for descending or `+` for ascending. Ascending is the default sort direction if no prefix is specified. This parameter cannot be used in the same query as the **bias** parameter.

      Returns:
      the sort

      Returns:
      the spellingSuggestions

    • tableResults
