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

I want to set a variable number and type of ValueRangeProcessors at run time based on a configuration file. But I seem to be running into (what I think is) a C++ scope issue. I tried just a simple test to see if I could add 5 VPs in a loop. Xapian::QueryParser qparser; Xapian::Query query; int vp = 0; while(vp < 5) { Xapian::StringValueRangeProcessor sproc(vp++);

Hello, I'm using the XS Perl bindings packaged with Debian stable and am interested in implementing my a custom ValueRangeProcessor (using DateTimeX::Easy for human-friendly date parsing) Unfortunately, I'm not sure if it's possible with the add_valuerangeprocessor API via Perl. Reading the XS/*ValueRangeProcessor.xs source files, I'm seeing "process_value_range"

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 My name is Shiv and I am student at IIIT-D ( http://www.iiitd.edu.in/ ) pursuing my undergrad education in Computer Science. I am currently in my final year. I am following the Xapian Gsoc guide ( https://trac.xapian.org/wiki/GSoC%20Guide#Mentoring). I have successfully checked out and built the code. I am trying out the python codes given at (

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

Hi Everybody, Here is the first version of my match for an ExternalPostList, it should apply cleanly to 0.9.5 and 0.9.6. You can use it by first implementing an ExternalPostingSource, then creating a new Query object passing a reference an instance of your implementation to the constructor, see query.h. The ExternalPostingSource implementation is reference counted, so when its no

hi! alls i have read an article about comments on Lucene. http://www.jroller.com/melix/entry/why_lucene_isn_t_that i have more understanding about Lucene through this article,especially its disadvantage or limitation. then i would like to question that are there similar disadvantages to xapian? any advice would be appreciated. baijl

Hi all, I found that the figure returned by MSet::get_matches_estimated() varies depending on how results are to be sorted. For instance, in my index, value 4 contains date and time in the format "yyyymmddhhmmss". For the same query, the number of results will be estimated to 20000+ when results are first sorted by date and time with set_sort_by_value_then_relevance(4) and to only 100

Hi all, public-inbox allows searching for git blob names (e.g. "badc0ffee") in patches. Initially, I chose to use add_prefix for probabilistic terms, since I assumed it could be a superset of what boolean searching offered. Unfortunately, it doesn't seem to be the case because stemming is interfering. So switching to boolean filtering seems to work; and it is fine for mechanical

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

Hi, I upgraded the Visual Studio SLN file to work with 2005 and had to make some changes. The first two have to do with the fact that the debug implementation of 2005's STL does all sort of validation, that's why they didn’t show up on 2003. I'm not set up for patch submission yet, but if somebody has time to review these changes that'd be greatly appreciated. Meanwhile

Gordan & David, Read about your latest work, and was thrilled to learn that both soft and hard mods are working. I bought the GTX 670 model in David''s article, I will be giving this a shot in a week. I was hoping to ask a few questions. 1. Is there a specific qemu version required (traditional or the new default)? 2. What (if anything) should be done after removing the resistors

Hola Jaap, I'm curious which version of the source are you working with? It sounds like you and I were working on the same problem yesterday, but I didn't see those particular compiler errors. (I saw a couple of other ones for which I submitted a patch). I did see errors like the ones you saw with the CVS LLVM 2.0 sources a while back, namely the missing < operator and the debug STL
