Frequently Asked Questions for ept-cache
========================================
Q: How does ept-cache related work?
A: The 'related' function of ept-cache relies on the Xapian index and works
like this:
1. Look up the Xapian records for all the package names given in the
command line;
2. Fetch all the tokens indexed for all the packages given, and build an OR
query with all those tokens;
3. Output the results of the query.
Q: How come the results of ept-cache seem to be in random order?
A: By default, ept-cache gives results in decreasing order of relevance.
Simply put, it gives the best results first.
ept-cache, however, allows query results to degenerate into less and less
approximate matches, and sometimes this leads to a point where results start
to look random.
If you want to have an idea of what is going on, use the --debug option to
see how the quality cutoff point is computed, then the --full option to
see the Search-Score: values. You can also use --cutoff to set a higher
quality cutoff value (default is to show results that are at least 50% as
good as the top result).
