      • searchForTerm

        public static List searchForTerm​(org.pentaho.platform.api.repository.ISearchable searchable,
                                 String searchTerm,
                                 int searchType)
        Searches an ISearchable object for a search term. The search rules are as follows: If the searchType is ISearchable.SEARCH_TYPE_PHRASE, then the fields in the table are searched for the exact phrase given. If the searchType is ISearchable.SEARCH_TYPE_WORDS_AND or ..._OR, then the following happens: a- Each word in the searchTerm is extracted and put into a list of search terms. b- Each search term is surrounded by the SQL wildcard '%'. So each search term becomes %term%. c- A dynamic query is generated searching each of the columns for each search term d- The searchType is used to determine the connector between each search term. e- The AND will match only if all of the terms appear in a specific column - cross-column searching using ..._AND will NOT work. In other words, if your search term is "East Sales", and your search type is ..._AND, a row will be returned if one of the columns contains East and the same column contains Sales. A row will NOT be returned if one column only contains East, and another column only contains Sales. This type of functionality could be obtained using a view that concatenates all of the searchable columns together into one large column, but this would be costly and database-specific.
        Parameters:
        searchable - ISearchable to search
        searchTerm - Search Term - see above for rules
        searchType - One of: ISearchable.SEARCH_TYPE_PHRASE,ISearchable.SEARCH_TYPE_WORDS_AND, ISearchable.SEARCH_TYPE_WORDS_OR
        Returns:
        A list of objects from Hibernate that met the conditions specified.
