similar to: How to search documents with certain values

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! 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

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

I was thinking about this some more: Is there a reason I can't just weight by some function of recency at indexing time? $weight = get_weight_based_on_recency(...); $tg->index_text($txt,$weight); If I wanted to allow the user the option of searching either in recency-weighted mode or not, I could index each document into 2 different databases, one with and one without. This avoids

I probably should've used boolean terms in addition to numeric values when indexing, but currently I have a set of numeric values[1] and trying to avoid having to reindex ~250GB DBs (and asking numerous users to do the same). Say I have a bunch of values which I want to filter a query against. If I had boolean terms, it could just OP_OR against the whole set. IOW, this is what notmuch does

Good afternoon I would like to ask if is possible somehow give more relevance to the recent documents in search results. I dont want to sort results according to the date, I still prefer relevance, but I would like to see recent documents with better scoring. I was trying to add search query using AND_MAYBE, which should use relevance from both subqueries, but it didnt add any benefit to the

Hi, I'm new to Xapian and wanted to know if it has a specific feature. I want to be able to check the relation between two terms on a page based on how close they are together on the page. I want to use a combination of n-gram based labeling and the "slop" feature found in Elasticsearch. Does Xapian have this/a similar feature? I haven't been able to find any programs that have

what is the fastest way to fetch results which are sorted by timestamp ? i want to use xapian as my search engine , use add_boolean_term(something) and add_value(0,sortable_serialise(get_timestamp())) to a doc. search through enquire.set_weighting_scheme(xapian.BoolWeight()) and enquire.set_sort_by_value(0,True) to ensure that the results are sorted by the timestamp. This method is ok , but

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 (

Hi Daniel, Thanks a lot for providing us your pointers. From the domain.xml(attached in my previous mail) which we have used for defining virtual guest i can see below lines <emulator>/usr/local/bin/qemu-system-x86_64</emulator> We were using same domain.xml in eralier libvirt version and the execution of cpu_stats command was successful. Now if we have to get "cpu_stats"

Hi, I'd like to know how we can choose the distance between two words that we search in a text. I know there is an "op_near" operator but I don't know how I can specified that the number of words between the two specified words should not exceed 10 or 20 or x words. I'm really sorry for my terrible English, I hope I'm understandable!

hi all, i want use sort_by_value to sort by "username". so in the indexing process i add the value i want sort by as value (lang is php) $document->add_value(0, 'value'); when i sort i got all specialchars at the beginning ? ? ? alf the values be indexed as utf8. what do i wrong? any suggestions? regards, sven

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 Daniel, Thanks for your immidiate reply. The starting of virtual guest was ok on our machine. We are facing this issue while executing the "cpu-stats <domain name>" command. I have collected the debug logs as you suggested and attaching the same. <<libvirt_testing_starting_VG.log >> --> Log collected while starting the virtual guest

Hi all, I am a new user to Xapian, and now we met such problem. In our case, a document has many attributes which is boolean value, for example( A, B, C ) , and our search query will use certain filter logic ( A == true and B == false ..) to combine with other search logic. We use MatchDecider to implement the filter logic, and now we met some performance problem, because our self-defined

hi all i am building an experimental php search app on top of xapian (using the xapian-bindings). i want to add a feature so that you can search within a search - search on a subset. i haven't yet started working on it, but as far as i can tell, there seems to be no easy way of doing this. can someone point me in the right direction? thanks alec

Hi Daniel, Thanks a lot for your reply. We have mounted all the cgoup controllers at "/dev/cgroup_<controller>" as mentioned below. ls /dev/ | grep cgroup cgroup_cpu cgroup_cpuacct cgroup_cpuset cgroup_mem On further debugging we dound that the "VCPU" directories are not being created for our domains and hence the comamnd "cpu-stats

Hi Team, I was trying to install the Nagios server in Centos 7. I had downloaded and unzipped the Nagios server and it's plugins file.
