## Advanced hunting query best practices
The following best practices serve as a guideline of query performance best practices and for you to get faster results and be able to run complex queries.
- Use time filters first. Azure Kusto is highly optimized to utilize time filters. For more information, see [Azure Kusto](https://docs.microsoft.com/connectors/kusto/).
- Put filters that are expected to remove most of the data in the beginning of the query, following the time filter.
- Use 'has' keyword over 'contains' when looking for full tokens.
- Use looking in specific column rather than using full text search across all columns.
- When joining between two tables - choose the table with less rows to be the first one (left-most).
- When joining between two tables - project only needed columns from both sides of the join.
