    • Method Detail

      • getUserQuery

        public java.lang.String getUserQuery()
        Returns the user query, which is the user-defined portion of the query, usually entered by the final user using front-end interfaces.

        The searcher can and usually perform a tokenization in the user query in the same way they do in the contents during the indexing process.

        Returns:
        the user query
        Since:
        8.1.0

      • setUserQuery

        public SearchQuery setUserQuery​(java.lang.String query)
        Sets the user query.
        Parameters:
        query - the user query. If the given user query is a blank string or null, it is equivalent to not having an user query.
        Since:
        8.1.0

      • getMaxRows

        public int getMaxRows()
        Returns the maximum number of hits to be returned by the query execution.

        Usually this setting is used to paginate the search results.

        Returns:
        the maximum number of hits
        Since:
        8.1.0

      • getStartAt

        public int getStartAt()
        Returns the number of the first hit to be returned by the query execution.

        Usually this setting is used to paginate the search results.
        This number is 1-based (the first result is the result number 1).

        Returns:
        the number of the first hit
        Since:
        8.1.0

      • getControlFilter

        public ISearchQueryFilter getControlFilter()
        Returns a query filter to be applied to the search.
        Returns:
        the query filter, or null if none was specified.
        Since:
        8.1.0
        See Also:
        #getControlQuery()

      • setControlFilter

        public SearchQuery setControlFilter​(ISearchQueryFilter controlFilter)
        Sets the query filter to be applied to the search.
        Parameters:
        the - query filter.
        Since:
        8.1.0
        See Also:
        #setControlQuery(String)

      • getUserQuerySemanticScoreWeight

        public double getUserQuerySemanticScoreWeight()
        Returns the weight applied for score based on user query semantic similarity with documents.
        Returns:
        the weight value.
        Since:
        16.1.0
        See Also:
        setUserQuerySemanticScoreWeight(double)

      • setUserQuerySemanticScoreWeight

        public SearchQuery setUserQuerySemanticScoreWeight​(double userQuerySemanticScoreWeight)
        Sets the weight applied for score based on user query semantic similarity with documents.

        Must be a value between zero and one. The default value is zero.

        The final score is calculated as the sum of the score generated by the semantic similarity multiplied by userQuerySemanticScoreWeight and the score of traditional keywords scoring multiplied by (1 - userQuerySemanticScoreWeight).

        So a value of one would use a score based on semantic similarity only, while a value of zero would use a score based on traditional keywords scoring only. While values between zero and one would use a score based on both scoring types.

        The use of semantic search depends on the AI being enabled on LumisXP. If it is disabled, this property is ignored.

        Note that, to use semantic similarity, other configurations in this search query must also be set.

        Parameters:
        userQuerySemanticScoreWeight - the value to set.
        Returns:
        this search query for method chaining.
        Throws:
        java.lang.IllegalArgumentException - if the value is not between zero and one inclusive.

      • getUserQuerySemanticMaxResults

        public int getUserQuerySemanticMaxResults()
        Returns the maximum number of results to try to obtain for a user query based on semantic search.
        Returns:
        the maximum number of results based on semantic search.

      • setUserQuerySemanticMaxResults

        public SearchQuery setUserQuerySemanticMaxResults​(int userQuerySemanticMaxResults)
        Sets the maximum number of results to try to obtain for a user query based on semantic search.

        Default value is 0.

        Note that this refers only to results based on semantic, the results based on traditional keywords search will still be returned. Use setMaxRows(int) to limit the total number of results returned.

        The use of semantic search depends on the AI being enabled on LumisXP. If it is disabled, this property is ignored.

        Note that, to use semantic similarity, other configurations in this search query must also be set.

        Parameters:
        max - Results the maximum number of results to try to obtain using semantic search.
        Returns:
        this search query for method chaining.
        Throws:

        public double getUserQuerySemanticMinSimiliarity()
