<human>:  How do I create filtered search with keywords in a database?
<bot>: 
1. Create a database index for the keywords you want to filter on.
2. When creating your search query, add parameters to the WHERE clause or other filtering conditions to filter on the indexed keywords.
3. Construct the query in a way that searches all areas of the database that contain the keywords you want to use for filtering.
4. Use SELECT, FROM and WHERE commands in your query to filter based on any additional criteria you wish, such as fields and field values.
5. Execute the query and review the results to ensure the correct records are returned.
