search for: add_valu

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 actu...

...ryone, 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 a list of slotno's anywhere that I can reference to? In a general sense is there any more programmer orientated documentation/tutorials rather than researcher orientated document than http://xapian.org/docs/ th...

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 at newgenstaticindex line 444 Thanks, Jim.

...indexing using PHP? With this, I can get an searchable index, but I have no idea how to set the fields, so that I can actually GET something back (with the underneath code, I just get a bunch of pid's back). $doc = new XapianDocument(); $doc->set_data($postrow['pid']); $doc->add_value(1,date('Ymd',$postrow['postdate'])); $doc->add_value(2,$postrow['author_id']); $doc->add_term("XAUTHORID".$postrow["author_id"]); $doc->add_term("XAUTHORNAME".$postrow["forum_id"]); $indexer->set_document($doc); $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 is there a faster way to do that ? Since i have millions of r...

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 add_posting (const std::string &tname, Xapian::termpos tpos,...

...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: Query (Query::op op_, PATH_ID, "/home/user/file.txt", "/home/user/file.txt") Is there a drawback to do such a query on a value? Or is a query on a value even faster? thank you Clemens -- Using Opera's rev...

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 help would be appr...

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

It should be noted that, you must pass original data as an parameter with send_response method because original data contains client address.

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 the second argument to set_sort_by_value, even though we shouldn't need to reverse the direction because a...
