I was wondering if there's an option to return statistics about distances from the query terms to the most frequent terms in the result documents.
The additional information I'm looking for is the average distance between these terms and my search term. So let's say I have two docs "the house is red" "I live in a red house" The search for "house" should also return the info the:1 is:1 red:1.5 I:5 live:4
Could you explain what the "distance" here is? Something like "edit distance"? Ah, I see: You want the textual distance between the search term and other terms in the document, and then you want that averaged, i.e. the cumulative distance divided by the number of occurrences. No idea if that functionality is available. However, the sort of calculation you want to perform requires the engine to not only collect all the terms to present as facets (much improved in 1.4, as I've just learned), but to also analyze each document (if I'm not mistaken) to determine the distance for each facet term from your primary query term. (Or terms.) The number of lookup operations is likely to scale as the product of the number of your primary search results, the number of your search terms, and the number of your facets. I assume this is an expensive operation. Michael Ludwig
