Expression evaluation error at function a!queryRecordType Cannot apply operator [INCLUDES] to field [englishconentnew] in a!queryFilter(). The valid data types for [INCLUDES] are [ Integer, (Decimal), Boolean, Date, Date and Time, Recieved Extra Long

I need to filter data in a record type but the field I want to apply filter on is extra long text it's throwing error . My actual requirement is I have to show the data in grid with serach options. In the grid data  800 rows are there so I am trying to use custom filters since I cannot use searchbox becase I am not using record data as data source that's because if the grid column need to display exra long text content it should inly use the query record type . so basically I am facing issue with extra long text but i need it because my data have characteres more than 9000 to 12000 . They all bascially html templates .Is there any way I can have option to filter the data not exact data but matches the query .
