Whoops, forgot to say, as Olly said, much of that could probably now be simplified with Xapian's snippet() function, which I can only assume did not exist back when all this was written! :) ATB, Matthew On Mon, 21 Sep 2020 at 09:28, Matthew Somerville <matthew at mysociety.org> wrote: > Hi, > > Ha, I was reading this thread thinking TheyWorkForYou (which I help > maintain)

Hi, Ha, I was reading this thread thinking TheyWorkForYou (which I help maintain) does highlight terms wherever they are, and then you mentioned it :) The code is open source; it is quite old and probably hair-raising, but as you say it does basically do what you want. Our Xapian database stores terms/boolean terms/values for the text, and for the document itself stores only an identifier. It

I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964). month X2000 X2001 X2002 X2003 X2004 X2005 X2006 X2007 X2008 X2009 1 1.600 1.010 4.320 2.110 0.925 3.275 3.460 0.675 1.315 2.920 2 2.960 3.905 3.230 2.380 2.720 1.880 2.430 1.380

Hi, I'm getting quite odd results using get_matches_estimated() that I haven't seen before; we've just added a bunch of new data to the database. Xapian 1.0.7, checkatleast is set to 100. The database will get new stuff added to it automatically around 8.30am BST, so it's possible this might affect the links I provide, I guess. But I'll note what is currently happening as

Short: get rid of the loops I use and optimize runtime Dear all, I want to calculate for each row the amount of the month ago. I use a matrix with 2100 rows and 22 colums (which is still a very small matrix. nrows of other matrixes can easily be more then 100000) Table before Year month quarter yearmonth Service ...

Hi List, The following code returns an "Error in as.POSIXlt.character(x, tz, ...) : character string is not in a standard unambiguous format" require(raster) require(rts) require(stringi) r <- raster(ncol=100, nrow=100) values(r) <- runif(ncell(r)) list(ID=seq(1:24),month=rep(str_pad(1:12, pad = 0,width = 2 , "left"),2),year=sort(rep(2016:2017,12)))->dt

Olly, Thanks again very much for helping me improve my understanding of Xapian and Omega. Thanks especially for pointing out that my idea of trying to generate a snippet from stemmed text lacking capitalization and punctuation would probably not produce a user-friendly result. But I'm still doubtful that expanding the sample size could be the right way to obtain excerpts from the document

Hi Herry, This is probably due to a call to strptime (or similar). No, it doesn't accept %Y-%m as a valid format. Maybe add a constant day to all the dates as that will work: dt<-list(ID=seq(1:24),month=rep(formatC(1:12,flag=0,width=2),2), year=sort(rep(2016:2017,12))) timelst<-paste(unlist(dt['year']),unlist(dt['month']),"01",sep="-")

Currently ExpandDecider::operator() and MatchDecider::operator() return `int' for no very good reason that I can see. It would be more natural to return `bool', since these classes are making a "yes/no" decision about whether to include a term in an ESet or a document in an MSet. The problem is that this can't be done without breaking existing user code which defines

Hi I am Rupesh from India. I have a huge directory of size 93.5 gb with 8500 mp3 files and 2000 sub directories. All these mp3s are speeches recorded by someone at 64 kbps. I want to compress these files recursively to opus using lame or another tool with 16 kbps bit rate and 11050 sample rate. I have compressed the above huge directory with above options using ffmpeg and the resulted

I would like to write a MatchDecider in C++ and expose it to PHP. I'm able to compile a simple extension and use SWIG to expose a simple function to PHP, but I can't seem to hit upon the right incantation to expose my MatchDecider class. I have a header file declaring my decider, MyDecider.h #ifndef _INC_MYDECIDER_H #define?_INC_MYDECIDER_H #include <xapian/enquire.h>

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 guys, I resently used xapian to sort some documents by distance between 2 points. I implemented a MatchDecider which work well. I now tried to implement a Weight scheme to put my document in ascending order depending on the distance... My information to calcul distance is in values in the document. How I can access document values from Weight to be able to add some sum_extra weight ??

Good afternoon I would like to ask if is possible in new version of Xapian some kind of subclasing MatchDecider in PHP. I am developing application where is very complex permission management. so it cannot be stored in fultext database. MatchDeciders are perfect for this purpose. But I dont know if is possible to use them in PHP even if SWIG now supports directors. Now Iam using

HI, all, I am a user of Xapian, and now I have a problem in using it. After using boolean terms to get some candidates of documents (still too much), we want sorted them by self-defined function which is used in Xapian::KeyMaker->operator(). But how can I get the serialise score in Xapian::MSetIterator object. c++ code likes this: class SortKeyMaker : public Xapian::KeyMaker { std::string
