5. Prefix query: This query is used to search for documents that contain a term that starts with a specified prefix.
6. Fuzzy query: This query is used to search for documents that contain a term that is similar to a specified term. It can be used to handle spelling errors or typos.
7. Boolean query: This query is used to combine multiple queries using Boolean operators, such as AND, OR, and NOT. It allows for complex queries to be constructed using a combination of other query types.
8. Match phrase query: This query is used to search for documents that contain a specific phrase in a field. It matches the entire phrase, including its order and position within the field.
9. Multi-match query: This query is used to search for a specific term in one or more fields. It can be used to search across multiple fields simultaneously.
