similar to: Xapian user search query syntax

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

Today we noticed that keywords can't be searched as prefixed terms. Or that's what it looks like anyway. I tested and, or, and not. ╰─% NOTMUCH_DEBUG_QUERY=y notmuch search 'subject:"and"' Query string is: subject:"and" notmuch search: A Xapian exception occurred A Xapian exception occurred parsing query: Syntax: <expression> AND <expression> Query

Dear Sir, I'm doing a literature survey on search engines. As Xapian is open source, I think I can get the information required by me.  I assume that your system builds a list of keywords and tags to every keyword the documents where it can be found. My questions are as follows: 1. What is the search algorithm used for searching the list of keywords that your search engine has?. Is it the

Dear Members of Xapian Project, Sorry for troubling you this time. It can be witnessed that xapian will store Document values with serialization approach when given value types meet float/double. Such an approach is deployed on sort_key related fields as well, where the xapian requires KeyMaker::operator() must return an serialized float/dobule variable. Then heap sort comes and ranks

This might be a little late but I was engaged in my university examinations. Moreover, I have an exam even today so apologies for the delay. Also, I had to change my project from weighting schemes to improve to improve estimated total number of results as weighting schemes was demanding a lot of time going through it. I would really appreciate if you could review my proposal asap.

All, I'm having some issues compiling omega. Here are the particulars I'm on win7, using cygwin 4.9.2 64 bit.

All, I'm trying to compile xapian core and bindings under cygwin. I have no issues running the configure script and then compiling core, but bindings is giving me some issues. I'm running the configure script for bindings as follows: in xapian-bindings-1.4.0 directory. ./configure XAPIAN_CONFIG=/home/John/xapian-core-1.4.0 --with-java and had two issues. The first I solved by doing

Dear Members of Xapian Project, Sorry for troubling you this time. This is Miao LIU, a postgraduate student working on information retrieval system related areas. I have been using Xapian (https://xapian.org) for quite a few months as the database and the searching engine in my IR system. I am currently facing a tough problem that I'd like to put all my posting lists in memory of my

Hi, In my explorations of Omega codebase, I have found that Omega is currently missing support for newer weighting schemes added in 1.4.1 (BM25+, PL2+, Dir+). I'd submit a PR addressing that but as I think I might be missing something so just wanted to check if there's a particular reason for that? P.S. Finally back after a long week. Been eagerly waiting for a weekend since the

Hi, I am currently pursuing my computing science bachelors degree at university of Alberta, Canada. My speciality lie in Information retrieval, machine learning and data mining. In order to get hands on experience with real world information retrieval systems, I would like to contribute to the Xapian project. I have been going through some of the project ideas in

I have a project that requires Xapian for a 32 bit arch, but Mac defaults to 64 bit. How can I configure Xapian core and Xapian python bindings to build 32 bit?

Hi, I have read the concurrency webpage from the Xapian documentation: http://getting-started-with-xapian.readthedocs.io/en/latest/concepts/concurrency.html But it is still not clear to me how to ensure thread-safety when using libxapian (C++ API). Usually when doing multi-threading many threads can read the same variable concurrently without locking provided none of the threads modifies the

Dear mentors and friends working on Xapian: Sorry for bothering you here, please excuse my rudeness. In order to clearly represent my thoughts, I think my words going a bit verbose, thus it is unsuitable to put them in the chat room or it would be a hell for the readers. This email consists of 3 parts, my self introduction (I'm new here) and two question I met while building Xapian from git.

Xapian is in the process of joining the Software Freedom Conservancy (https://sfconservancy.org/), but one thing we need to sort out before we can finalise this is some sort of more formal project leadership structure. James Aylett and I have discussed this with Bradley Kuhn from Conservancy, and we think the most appropriate model currently would be a small group of at least 3 (to avoid deadlock

Hi All, I am trying to compile xapian-core from the git source tree and after running the autoconf successfully while running configure getting the following error configure: creating ./config.status config.status: error: cannot find input file: `Makefile.in' can some one help me to solve this problem.
