similar to: Sorting results by a "sort expression"

Hi all, I am trying to implement a scheme where documents in an MSet will be sorted based on relevance as well as geographical distance from a given (non-fixed) point. I understand that this can be accomplished by using PostingSource in order to implement a custom weighting scheme that would combine BM25 weighting and distance. The problem is that I am using perl and PostingSource is not

Using MultiValueSorter, I can sort by key1, key2, relevance; or relevance, key1, key2. But AFAIK, I can't sort by key1, relevance, key2. Unless I spool out the entire result set or write some C++. I wonder if we need a new 'sort by' function that accepts any combination of keys and relevance in any order? The function would make it's own optimisations (ie is relevance first or

Hello all, I''m currently designing a web app in Rails that lets me keep a directory of free/opensource computer games. Each game has attributes like name, website, review, etc., but each game can also be associated with a set of genres and gameplay elements. The main three tables I''m working with are "games", "genres", "elements",

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

Ahoy, I made this pager, " def list @item_pages = Paginator.new self, Item.count, 10, @params[''page''] @items = Item.find :all, :conditions => "category_id = #{params[:condition]}", :limit => @item_pages.items_per_page, :offset => @item_pages.current.offset @categories = Category.find_all

Hello, this is a question that could be answered by collaborators of the Ruby bindings. Today I've played around with the Xapian::MultiValueSorter class. I've set everything up and then I tried following on an instance of Xapian::Enquire: : enquire = Xapian::Enquire.new(database) enquire.query = options[:query] : sorter = Xapian::MultiValueSorter.new sorter.add(0, true) sorter.add(1,

Ok, I searched but couldn''t find anything and I even tried the RoR IRC channel with no help. I get this error: uninitialized constant Airport I used this code which I got from the RoR site. helper :sorting def list @sorter = SortingHelper::Sorter.new self, %w(icao host_id name), @params[''sort''], @params[''order''], ''icao'',

Hi there, I have a xapian index whose results are being sorted by a value, with (PHP bindings): $enquire->set_sort_by_value($sort_data_value); This is because I want the results returned in chronological order of publication date. However, I now have a need to have certain results be 'sticky' at the top of the resultset, regardless of their publication date. Obviously there are

Hello, In order to solve that problem of sorting numerics made characters there is package stringr, functions str_sort and str_order. library(stringr) set.seed(2447) x <- sample(11L) sort(as.character(x)) [1] "1" "10" "11" "2" "3" "4" "5" "6" "7" "8" "9"

Hi, i have a lot of troubles when i try to build rpm?s out of the glusterfs 3.1.3 tgz on my SLES Servers (SLES10.1 & SLES11.1) all is running fine i guess until it try?s to build the rpm?s.

I need to import several ascii files in fixed format with two different record types. The data comes from European Labor Force Surveys, wich is a household survey. The first record type is for people over 16 years, and the second much sorter is for people aged 15 or less (this record has a filler with several blanks to get the same record length). The files tipically have 160000 records, with 176

Hi, I'm not sure this is a bug, so I thought I'd bounce it off the help group first. I had a dataset which I was subsetting, and occasionally I get an empty subset. If I don't check for emptiness and go straight to a which.min call on the subset, the program gets a big negative number back. One-line Example: > which.max(NULL) [1] -2147483647 This caused an indexing

Hello. Was just curious to know if anyone is working on a graphical interface to Asterisk using X windows, or something else similar. Thanks!

Hello, I have somewhat of a weird data set and am attempting to create a barplot with it. I have 8 columns with different variables and their percentages. I have 1 column with representations of 4 different treatments the variables undergo. I also have 1 column with year the data was recorded. I want to create a bar plot that plots all 8 variables grouped by treatment and year. I've tried

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

Hello! I have a sip device that is sending in the SDP: rtpmap:98 g729a It does not seem like Asterisk is negotiating the codec properly, because while the call rings, the rtp lines fail. However, on other sip devices that have "rtpmap:18 g729" in their SDP, things work fine with Digium's commercial g729 license. How do I get "98 g729a" recognized by Asterisk? Thanks,

I have been using ddply to do aggregation, and I frequently define a single aggregation function that I use to aggregate over different groups. For example, require(plyr) dat <- data.frame(x = sample(3, 100, replace=TRUE), y = sample(3, 100, replace = TRUE), z = rnorm(100)) f <- function(x) { data.frame(mean.z = mean(x$z), sd.z = sd(x$z)) } ddply(dat, "x", f) ddply(dat,
