search for: add_values

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

Hey everyone, I am brand new to Xapian so forgive me if I am just being noob. I looked over the sparse documentation for the Xapian library and its PHP hooks and I am really confused how to complete my index. I understand how to add documents etc etc etc and how to build queries but how I do specify in add_value what field type xapian should take (i.e. tokenized, unindexed, indexed)? Is there

I attempted to use the sortable_serialize function from perl, however doesn't seem to exist. The only occurrence of the string "sortable" in the /usr/local/perl/5.10.1/Search/ tree is in the pod in Xapian.pm. What am I doing wrong? use Search::Xapian; ... $doc->add_value(4,sortable_serialize($recdate)); Undefined subroutine &main::sortable_serialize called

Currently I have the following indexscript: pid : unique=Q boolean=Q field=pid postdate : field=startdate author_name: unhtml boolean=XAUTHORNAME field=author author_id: boolean=XAUTHORID field=authorid url : field=url sample : weight=1 index field=sample How can I create the same indexing using PHP? With this, I can get an searchable index, but I have no idea how to set the fields, so that I

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

Dear, guys: I am a beginner of Xapian, when reading the documents, I encountered follow questions. (1) I see the Xapian::Document has a method void add_value (Xapian::valueno valueno, const std::string &value) What's the purpose of this method? Document will related to the terms, but what's the purpose of this? (2) add_posting method will add term to a documents. void

Hi, I want to update a document. The document is identified by the document path e.g. /home/user/file.txt. To find the doc id by the path I need to assign the path to the document. In the FAQ is supposed to add the doc id (the path) as a term to the document. My idea is to at the path as a value by #define PATH_ID 0 add_value(PATH_ID, "/home/user/file.txt") and then do a query:

In a recent post, someone asked about storing "metadata" in a document. My guess would have been to use add_value. Olly's recommendation was to use set_data. What are the general guidelines for deciding whether to use values or data in a document? Garrett

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've some problems converting a xapian db, created with core 1.1.3 (using chert), to the new chert format. I'm using xapian-chert-update, compiled from the core-1.2.4. The conversion seems to run without errors: #./xapian-core-1.2.4/bin/xapian-chert-update old new postlist: Reduced by 33.3333% 16K (48K -> 32K) record: Size unchanged (8K) termlist: doesn't exist position: Size

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

Hi, I have a model which has properties, these are your standard name/value pairs, but also have attributes that affect how I want to store them in ferret. I was using 0.9.5 with 0.2 of aaf, which seemed fine, I just copied and pasted (yes, I know, ick) the to_doc method and added code to iterate though the properties that that model had, and add relavent fields to the document. It seems

Hello, is there a way to optimize sorting by certain values for queries which return a huge amount of results? For example, I just want a simple query that gives me the 200 most recent emails out of millions. The elapsed time for get_mset increases as the number of documents ($n * 2000) increases. I suppose I could store a pre-sorted set using SQLite or similar. Thanks in advance for any

...uot;send_response" to send the result back to client ( rails in our case ). It should be noted that, you must pass original data as an parameter with send_response method because original data contains client address. Following code snippet, would ask bdrb to execute method ''add_values'' in ''foo_worker'' with arguments ''10+10'' and return the result. MiddleMan.send_request(:worker => :foo_worker, :method => :add_values,:data => "10+10") You can also use register_status as described in following snippet to r...

Hi All, I need to update or delete some documents from a Xapian database. and I haven't been able to find anything in the API , Is there a way to do it ? What would be the easiest way to do it ? Thanks.

I have a search in perl that looks a bit like: my $qp = new Search::Xapian::QueryParser(); $qp->set_stemmer(new Search::Xapian::Stem("english")); $qp->set_stemming_strategy(STEM_SOME); $qp->set_default_op($defaultop); ... my $par = $qp->parse_query($query); my $enq = $xDatabase->enquire( $par ); and in the db create script: my $stopper =

Dear all, I am working on a very simple project, in which I wanna get the title from the document. For instance, this is what I have done so far. ///////////// code? for building the index file ??????? # Load content ??????? content = open(filePath).read() ??????? # Prepare document ??????? document = xapian.Document() ??????? document.set_data(content) ??????? # Store fileName ???????

Hi, I'm trying to sort a list of results alphabetically, but it's coming out in the wrong direction. Indexing is done like this (PHP bindings): // Tag name as a value (for sorting) $doc->add_value(2, strtolower($obj->tag)); And searching like this: $enquire->set_sort_by_value(2); But for some reason, the results are coming out Z-A, not A-Z. I've tried setting true as
