## Before you begin
|
||||
To maximize the advanced hunting capability, it's a good idea to understand the following query best practices.
|
||||
|
||||
### Query best practices
|
||||
- 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.
|
||||
- Prefer 'has' keyword over 'contains' when looking for full tokens.
|
||||
- Prefer 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.
|
||||
|
||||

A typical query starts with a table name followed by a series of operators separated by **|**.
