While querying with WHEN =

SELECT * FROM books WHERE name='8b481c6e-48a0-4552-a624-9e8fbad4f930';

Result

cqlsh:hipi> SELECT * FROM books WHERE name ='8b481c6e-48a0-4552-a624-9e8fbad4f930';
 author_id                            | name                                 | created_at                      | status

But while using with LIKE

SELECT * FROM books WHERE name LIKE '%8b4%';

Result

InvalidRequest: Error from server: code=2200 [Invalid query] message="LIKE restriction is only supported on properly indexed columns. name LIKE '%8b4%' is not valid."

To use LIKE filtering in CQL, you need to build your index as a SSTable Attached Secondary Index (SASI). SASI indexes are considered to be "experimental," so they are disabled by default. To enable them, flip this setting in the cassandra.yaml for all nodes, and restart the cluster:

sasi_indexes_enabled: true

Next, create your index like this:

CREATE CUSTOM INDEX books_name_idx ON abc.books (name)
    USING 'org.apache.cassandra.index.sasi.SASIIndex';

Then, this should work:

> SELECT * FROM books WHERE name LIKE 'Mastering%';

 author_id | name                           | created_at                      | status
