What does the Sphinx SQL Configuration item SQL statement $start and $end mean?

For example:

For example, what does the $start and $end in this configuration mean?
Is the parameter passed? Or do you initialize the definition yourself?
What is the meaning of $start and $end?

Is it necessary for me to use $start and $end in the Sql_query configuration like (that is, indexer SQL execution statements?). ）

Beginner sphinx, tell a bit of chaos.

ID of the Sql_query_range setting

Upstairs, it should be the function of the query.

Feel that the landlord should be in the establishment of the index when the problem arises.

ID range limit for index data
For example, 1 million data, I want to index the data between 1-10w.
Want to index all data, usually min (id) and MAX (ID)
