That clarifies it perfectly.
Thanks for the example!

In general, lookthroughlimit is much stricter than sizelimit.

For example, let's say a user wants to do an unindexed search for (description=*something*). Let's say that there are 5000 users and 1000 users who have a description attribute that matches *something*. The server will have to search through every entry in sequential (indeterminate) order to find matches.

If you set lookthroughlimit to be 1000, and set sizelimit to be unlimited, the server will look at up to 1000 entries looking for description=*something*. Some of them may match, some of them may not, and the server will return 1000 or fewer entries (indeterminate). The server is limited in the amount of work it performs searching through the database.

If you set sizelimit to be 1000, and set lookthroughlimit to be unlimited, the server could look at all 5000 user entries, until it finds 1000 entries which match, at which point it will terminate the search and return the 1000 entries to the user.
