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). |
