Hi! Alls ???? i have read code of xapian more than one month,i leant a lot from your code both form design of search engine and code details. ???? however, something make me in a puzzle. ? ?? Take? RefCntBase as an example, it seems that it is a "kernel" of xapian, as many classes inherit from it. But,what is it funtion? why is it so important? ???? Another confusion is about

QueryParser is great, but I would like to make a query myself, so I can filter results by a specified value (in this case restricting by epoch time after a certain value) My code looks like this, and compiles, and appears like it should work according to the perl source:     my $query = $qp->parse_query($querystr);     if ($datefilter) {         my $filterepoch = time() - ($datefilter

Hi all, I am creating Xapian documents and adding a unix timestamp to each document as a value using the doc.add_value method. When I search my Xapian database, I want the option to only search documents with a timestamp within the last year. Is there a way to search across documents with a value greater than a specified value string? Or is there a better way of doing something like this? Any

Dear All, Is there an LLVM analysis pass that can, given an LLVM integer value, tell me the minimum and maximum values that the value will be at run-time? Conservative answers are fine, and execution time isn't too important, so the more accurate it is, the better. Thanks in advance. -- John T.

Hi all, I have jotted down a plan for how to handle or add Bi-gram in Query Object though QueryParser. PFA as a sequence diagram which depicts what i got to know about how parser works and query is build from tokens provided by the lexer.I have highlighted some area in blue where i think there is possibility of having bi-grams.While Integrating bi-gram in the Parser ,Query our aim is to generate

Thanks that helped :). I am still trying to cover add_value some more though since I seem to not understand it totally. I guess it is because I am used to Lucene and Sphinx and Solr and it appears that Xapian seems to attach the type of value stored more on add_value. Like for example I am still a bit confused on how slotno actually works and what it actually is. I think the main thing is
