search for: document_id

Hi All I have made my xapian indexer automatically create new indexes once it reaches X documents in each, and for each document that I add to each sub-index, I record its document_id and its index_id (relating to what index the document ended up in). writabledatabase_add_document() returns document_id:s beginning from 0 for each new index when you add new documents, like you would expect. So far all good. Here is the problem: when I search through the indexes together (usin...

OK, I'm indexing my data with the scriptindex. I want to be able to restrict the search by the category field. Do I need to do anything to the data itself? Like, literally prefix it with the characters "XC"? Below is my indexor for scriptindex and the my php code... document_id : field=ref unique=Q boolean=Q search_id : field=document_id index=S document_title : field=title weight=3 unhtml index landing_page : field=landing_page document_text : field=document_text unhtml index abstract: field=abstract category: field=category boolean=XC - - - - - - php - - - - - - /...

...returned by a query should get more weight because they are getting clicked more often) in xapian? Is this what the rset class should be used for? I could write a php app to do adaptive results scoring for separate words (just recording the clicks and then have a cron:ned script add weight to the document_id:s for the recorded words), but I don't see a clear way to do this for phrase searches (as in document_id x should get more weight if the search is for (and only for) 'xbox console', not 'xbox' or 'xbox games' or whatnot. Thanks Alec

Hi guys I have implemented xapian on a website, and it currently has about 2M items in its index. Its all been working quite nicely so far, until I tried removing some old items from the index (removing items when the index was smaller was no problems at all). When I try to remove them now (using writabledatabase_delete_document() via php), it halfway freezes up the machine, and the apache

...ntroller.rb @paginator, @documents = paginate(:documents, :order => @sort_by, :include => :category, :per_page => default_per_page) I keep getting the following error: ActiveRecord::StatementInvalid in DocumentsController#component Mysql::Error: #42S22Unknown column ''categories.document_id'' in ''on clause'': SELECT COUNT(DISTINCT documents.id) FROM documents LEFT OUTER JOIN categories ON categories.document_id = documents.id Can anyone help me and point out where i am going wrong? -- Posted via http://www.ruby-forum.com/.

...ument.find(:all, :conditions => [''group_id in (?)'', session[:group_ids]) ? Question 2: These documents are dynamic, so they are deleted, updated, edited etc. How do I handle indexing in these circumstances? Delete all and recreate -or- is there a way to just delete an index by document_id and recreate it just for that document. I am going to try this in the app but before I took the plunge I thought I''d ask first. -tia, bakki PS: the app will be used by separate client companies, so on one server we will host the app in multiple virtual hosts(separate rails app instance...

Hi, Is the following command used to increase the memory or any other command when a background R job is run?

I need to give users the ability to optionally add metadata to documents. Another way to state this is the fact that users need to add at least 5 categories to a document. Basically what I want to do is dynamically add metadata (or categories) to a document on an ad hoc basis. Here are the options that I have thought of: **Option 1:** Should I do this by dynamically creating new table columns in

...s (and, by extension, an Option belongs to a Document). Each document may have a different number of options, hence why I made it a separate model. Each document has the following fields: "name" and "content". Each option has the following fields (aside from the obvious "document_id"): "name", "hint", and "value". I would like to create a form for a document, with nested fields for that document''s options. The tricky part is that I would like to use the fields listed above in my builder, for instance for the hint or label. I'...

I am looking to have a number of categories populated from my results of a search. For example, searching on "sport" would display all results for sport. I want to also have a number of categories to refine the documents down. So by clicking on the "Fishing" category or the "Shooting" category, I would only see the results on sport around that category. Now for

Hi, The following code, from Angelo Canty article on line "Resampling Methods in R: the boot Package, 2002", works fine for Angelo Canty using R 2.6.0 on Windows XP. It also works for me using R 1.2.1 and S-PLUS 2000 on Windows XP after installing the S-PLUS bootstrap library, with slight differences in my outputs. > library(boot) > library(survival) >
